Especially departures, it seems, as the massive restructuring of the digital units of News Corp. (NWS) keeps shaking out.

Top engineer Max Engel (pictured here), who ran the social networking site’s open initiatives, for example, is leaving to join the new stealth start-up being helmed by ex-MySpace employees, including former COO Amit Kapur.

In a blog post on his Web site yesterday, titled “Farewell, MySpace…,” Engel did not say where he was headed, but noted:

“While MySpace presented opportunities through their scale and reach, I’ve spent the past 3 years at large companies, and now I’m ready to go small and give the startup life a try.”

In addition, while I was poking around on this story, sources also told me that there are more higher-level departures in the works, including those whom the new team of execs at Beverly Hills, Calif.-based MySpace had kept in place, despite a recent round of layoffs.

Those execs include Tom Andrus (pictured here), who was a key product exec in the last regime at MySpace, sources said, but is poised to go. His former charge was as SVP of product management under MySpace co-founder Tom Anderson.

While Anderson remains at MySpace, his role has been changed and product is now headed by Jason Hirschhorn, and Andrus reportedly decided recently that he did not want to stay at the company in a lesser role.

Andrus is also listed as a developer at Gray Ghost Ventures on LinkedIn.

In the longer term, sources said it is also likely that once he completes the work to downsize MySpace’s international operations–which were cut drastically–its head, Travis Katz (pictured here), will move on in the fall.

While some thought he would leave during MySpace’s international layoffs several weeks ago, he did not, given all the work involved in closing down a lot of operations there after 67 percent the staff abroad was cut.

Katz, sources said, is preparing to move to California in the next several weeks and is interested in working for a start-up, after many years at News Corp.

Lastly, on the goodbye train, is MySpace Music’s SVP Strategy and Global Marketing, Jamie Kantrowitz (pictured here).

She had previously worked as a top exec in MySpace’s international business.

Not everyone is bidding adieu, though, although they are moving chairs.

Dan Fawcett (pictured here), president of Fox Digital Media, is likely to be moving to work with News Corp. digital head Jon Miller as his general counsel and right-hand man at the Fox Interactive Media division.

The former GC, Mike Angus, has moved to FIM’s Fox Audience Network, run by Adam Bain.

FIM, of course, is being rejiggered into a new smaller unit, as I previously reported, and is likely to be renamed simply the Digital Media Group.

(Full disclosure: FIM is owned by News Corp., which also owns Dow Jones–owner of this site.)

Finally, Owen Van Natta is about to win out over a founder.

The former Facebook COO (pictured here) is poised to become the CEO of MySpace, replacing co-founder and current CEO Chris DeWolfe.

DeWolfe will likely get a title as a special adviser to MySpace in a deal that is still coming together.

Settling all the specifics could take at least a day and there is always the possibility that this changing-of-the-guard deal could fall apart. But multiple sources close to the situation said it is more just a matter of ironing out the details.

Thus, the die seems cast for Van Natta to take over the thorny job of rehauling MySpace, which is owned by News Corp. (NWS).

(News Corp. also owns Dow Jones, which owns this Web site).

In a post this morning, MediaMemo was the first to name Van Natta as the only candidate in the running to take over as leader of MySpace.

It’s familiar territory for him.

Van Natta never got the big job at Facebook, which is under the firm control of founder and CEO Mark Zuckerberg.

But Van Natta–who got to Facebook in its early days after stints at various companies, including Amazon (AMZN)–was a key early player in making the social-networking site into the juggernaut it is today.

He played a large role in its advertising and investment deals with Microsoft (MSFT), for example, as well as in hiring many of its current execs.

But, like many at Facebook, Van Natta left Facebook in early 2008 under tense circumstances, although he now is on good terms with Zuckerberg and others at Facebook.

Maybe not any longer.

In a delicious digital irony, he will be taking on Facebook head on, as MySpace–once the momentum player in the space–tries to regain its step against Facebook.

Van Natta is currently CEO of music start-up Project Playlist and it is not yet clear what will happen there. When he was previously talking to MySpace about running its music site, there was speculation that it might buy the start-up.

Today’s developments have happened quickly and without a lot of advance planning.

The talks to complete this deal are being led by new digital boss Jon Miller (pictured here), who came to News Corp. last month.

News Corp. officials declined to comment on the developing situation.

But sources said that Miller hadn’t been planning on getting rid of DeWolfe in the near future, and until yesterday, he was still evaluating his options.

News Corp. CEO Rupert Murdoch had once treated DeWolfe as a favorite and gave him significant autonomy at MySpace.

But Murdoch, who brought Miller on, has been leaning toward a change in leadership as MySpace’s traffic has stagnated and its buzz and momentum have moved to Facebook.

Under DeWolfe, many have felt it has dropped the ball on innovation and in making key improvements to its technology and features.

Worst of all, MySpace’s lucrative $900 million search advertising deal with Google (GOOG) is also coming to an end, a deal that essentially paid for the News Corp. acquisition.

Recently, several key execs have left too, including COO Amit Kapur.

In general, the social-networking giant has had an air of decline about it, despite its still-enormous size.

Nonetheless, Murdoch had left the decision about the site’s leadership to Miller, his new hire, sources said.

Miller had been talking to many and was indeed leaning toward putting a new CEO in place, but not in this fashion. He had hoped to work out the transition with DeWolfe, said several sources.

Miller himself had been badly treated, when Time Warner (TWX) dumped him as CEO of AOL several years ago. Ironically, the media giant just ousted the execs who ousted Miller.

But Miller’s options narrowed last night, once TechCrunch ran a story claiming that News Corp. had hired a headhunting firm to “scour for possible replacements” for DeWolfe.

News Corp. hadn’t actually hired a headhunter at all, but the story spooked DeWolfe into calling Miller to ask what his plans were. That conversation led to today’s negotiations.

Van Natta is well known at News Corp. and was, at one point, the leading candidate to head up MySpace Music, which launched last fall, and the two sides held extensive conversations.

But Van Natta did not like the job’s org chart: Rather than a standalone company, MySpace Music is simply a unit of MySpace, reporting to DeWolfe.

MTV executive Courtney Holt eventually took the job.

Van Natta is intertwined with MySpace in other ways.

Project Playlist, the free music-streaming site he took over last fall, has seen traffic plummet after MySpace, along with Facebook, cut off the sites’ access to their users, a move prompted by lawsuits from several major music companies.

Van Natta has made some headway at extracting the company from its legal mess, which predated his hiring, and he has hammered out a settlement with EMI Music Group.

But Playlist is still being sued by other music labels.

And, even music sites that aren’t in legal trouble are struggling to keep their heads above water.

Thus, plenty of Silicon Valley watchers–including BoomTown, who calls Van Natta periodically to ask why he seemed to enjoyed the pain of running an online music business–have wondered why Van Natta landed at Playlist in the first place, and have speculated that he has been looking for a way out.

He has been on the short list for many big Web jobs at places like Microsoft and other Silicon Valley start-ups, but has not bitten until now.

Amit Kapur, who was elevated to COO of MySpace early last year, will be stepping down from the position. He’s leaving the company to start a new venture with two other MySpace executives, Jim Benedetto, SVP of Engineering, and Steve Pearman, SVP of Product Strategy.

Selected by CEO Chris DeWolfe, Kapur had been charged with helping drive innovation in content and also business development at the social network, which has lately seen some of its thunder stolen by the faster-growing Facebook.

MySpace declined comment.

But here is a video interview I did with Kapur, as well as DeWolfe, at a MySpace party in San Francisco, right after he got his COO title.

(News Corp. also owns Dow Jones, which owns this site.)

BoomTown just got to Paris, as in France, to attend and moderate sessions for the third annual Le Web conference.

Le Web is organized by Loïc and Geraldine Le Meur, with 1,500 people signed up to hear a range of Internet players, many of whom are from the U.S., tomorrow and Wednesday.

U.S. speakers include TED’s Chris Anderson, News Corp. (NWS) social-networking site MySpace’s Amit Kapur, Marissa Mayer of Google (GOOG), Linda Avey of 23andMe, LinkedIn’s Reid Hoffman, and Dan’l Lewin of Microsoft (MSFT).

And some interesting European execs include France Telecom Orange Chairman and CEO Didier Lombard, and Jacques-Antoine Granjon, CEO and co-founder of a very interesting fashion sale site, Vente-Privee.com.

Of course, there’s a passel of bloggers here like BoomTown. I’ll be interviewing Werner Vogels, CTO of Amazon (AMZN) and well-known Israeli entrepreneur Yossi Vardi.

Besides this conference, Loïc Le Meur has been trying to make a go of it with his San Francisco-based start-up Seesmic, which–like a lot of Web 2.0 companies–has recently made cutbacks. See my video interview below with him in better times, when I visited Seesmic in February.

You can also watch the conference streamed live from its site. More shaky–but Frenchtastic, although no lip-synching extravaganzas for me!–videos from me at Le Web to come, of course.

[Full disclosure: My partner, Google exec Megan Smith (you can read all about it here in detail), is judging a start-up competition at Le Web on Wednesday. But I am trying to find an excuse not to go to that panel, because I always nod off at those things, even if the crazy version of Britney Spears were a judge. Instead, I hopefully will be enjoying the lovely artwork at the Louvre right then.]

Last night, BoomTown checked out the new space MySpace is renovating for its soon-to-open San Francisco office. The occasion was a party the social-networking site held for developers as part of its recent platform launch.

In other words, the night MySpace started kissing up to the widget makers with tasty burgers and big techie hugs.

And those widgeteers showed up in full force for the sandbox-themed event (I even brought my kids, who played in the actual sandboxes set up and made quite a mess!), including Slide’s Max Levchin, RockYou’s Jia Shen, Google’s OpenSocial guru Joe Kraus (who apparently did not get to go to Disneyland with the rest of the company) and many others.

Also in attendance were MySpace’s top brass, including Chris DeWolfe and Tom Anderson, as well as its new COO Amit Kapur and lots of other MySpace minions, coming up from Los Angeles.

MySpace –which is owned by News Corp., which also owns Dow Jones, which owns this site–is still the largest social network both in terms of users and page views. But its growth has been slowing and, worse, its thunder has been stolen by the faster-growing and more-hyped Facebook, based in Silicon Valley.

Last year, that competition was in sharp relief when Facebook Founder and CEO Mark Zuckberberg opened its platform up to third-party developers. The crafty move sent widget makers into near ecstasy. (”He likes us, he really likes us!”)

And while widgets were actually on its site for a while, MySpace had not formalized those relationships with programmers and even battled with them, which has been the source of consternation in the development community.

Now, the company is trying to mend those broken links and has built more organized systems for letting software developers build a range of new services for its users. It also partnered with Google in the search giant’s efforts to open up the development process with its OpenSocial initiative.

Time will tell if the make-nice efforts by MySpace will work, but here’s a video of the party (and in the following post here features longer interviews with DeWolfe and Kapur):

BoomTown went and did a video of the event here, where the trendy, Beverly Hills-based social-networking site made nice with the geeky widget makers of Silicon Valley.

And we also talked to MySpace Co-Founder and CEO Chris DeWolfe and new COO Amit Kapur:
