Champagne wishes and caviar dreams are now but a memory for billionaire shareholder-activist Carl Icahn, who lost about $125 million today by selling off 16 percent of his ever-losing stake in Yahoo.

The sale of 12.7 million shares at just under $15 a piece is a far cry from the hopes that the famously prickly Icahn had when he started his quest to bring about change and riches for himself by investing in the stock of the turmoil-plagued Internet giant in 2008.

Icahn went far in waging a proxy fight for control of the Yahoo (YHOO) board.

He got on the board all right, along with nabbing two other seats, but that’s about all he got.

No $40-billion-plus sale to Microsoft (MSFT), a much lesser search deal and yet another troubled investment for Icahn in a year of troubled investments.

As it turned out, he came to Silicon Valley, he saw, he did not conquer.

Nonetheless, Icahn still has a 4.5 percent stake in Yahoo, or about 63 million shares.

In a filing with the Securities and Exchange Commission, Icahn said the move was to balance his portfolio, but that he still was bullish on Yahoo, its recent search deal with Microsoft and Yahoo CEO Carol Bartz.

Which is also rich, given that she just dissed him again publicly in a piece in Forbes, tossing off a saucy insult:

“Icahn is just another shareholder. What’s he going to do, fire me?”

Well, in a tiny little step today, he kind of did that to Yahoo.

BoomTown just could not resist making the obvious literary pun on the debut of Peter Kafka’s new daily blog, MediaMemo, on AllThingsD.com.

(He is pictured here.)

For those who were not dragooned into reading existentialist writers in college, I am referencing “Metamorphosis,” about a man who turns into a bug–except that the process is fraught with so much more meaning.

And thus it will be in Peter’s column, as the most excellent writer and reporter plunges into the topic–as he writes in his first explanatory post–of “the ongoing battle between the established media business and the technology that is reshaping it day by day.”

It is transformative, to say the least, from someone who will lead you through it with the kinds of standards, accuracy, great writing and insight that I hope you have come to expect from this site.

While Peter’s impending arrival to ATD was announced in mid-September, he actually debuts today and will be posting many times daily.

As I have previously written, Walt Mossberg and I have long wanted to bring in someone located on the East Coast and away from the echo chamber that Silicon Valley can be, because we both feel the ongoing digital revolution is taking place over a number of key industries all over this country and the world.

With extensive connections across the media, advertising, entertainment and tech sectors, Peter will be doing original reporting, getting scoops, doing interviews, making videos and providing much needed and clear-headed analysis that he is so well-known for.

Peter has been working at Silicon Alley Insider, most recently as its managing editor, since mid-2007. The first hire at the start-up tech business analysis site, he has focused on enterprise and beat reporting, as well as breaking news.

Previously, he spent 10 years as a reporter and editor at Forbes and Forbes.com covering media and technology. (You can read more of his bio here, along with his ethics statement.)

Walt and I are thrilled that Peter is coming onboard to join the rest of the strong ATD team, which includes: John Paczkowski, author of the rocking Digital Daily column, who formerly wrote the award-winning blog, “Good Morning Silicon Valley” at the San Jose Mercury News; and Wall Street Journal reporter Katherine Boehret, who writes the most excellent weekly Mossberg Solution column.

And we hope you will soon find–via following Peter regularly–why we are so very excited to welcome MediaMemo to the site.

Although we did not raid the offices of Silicon Alley Insider and “steal” Peter Kafka, as the fanciful SAI kingpin Henry Blodget alleges–had it been a raid, BoomTown would have properly hog-tied Blodget so he could not make such spurious allegations!–it is true that SAI’s current managing editor (pictured here) will be coming to work for us at AllThingD.com soon.

Indeed, Walt Mossberg and I, as well as the rest of the ATD team, are thrilled that Peter is coming onboard at the end of October. He will write a daily still-unnamed new media blog from New York City.

Walt and I have long wanted to bring in someone located on the East Coast and away from the echo chamber that Silicon Valley can be, because we both feel the ongoing digital revolution is taking place over a number of key industries all over this country and the world.

Peter was our first choice and has been on my must-read list since I began this blog. He is sharp, witty, confident and has the kind of reporting and writing chops that we think are key to giving readers high-quality, standards-based content they can trust.

With extensive connections across the media, advertising, entertainment and tech sectors, Peter will be doing original reporting, getting scoops, doing interviews, making videos and providing much needed and clear-headed analysis that he is so well known for.

Peter has worked at SAI since mid-2007. The first hire at the start-up tech business analysis site, he has focused on enterprise and beat reporting, as well as breaking news.

Previously, he spent 10 years as a reporter and editor at Forbes and Forbes.com covering media and technology. There he launched two tech columns, coordinated the video staff and represented Forbes on industry panels and in TV appearances for CNN, BBC and CNBC.

Peter was also a staff reporter with City Business in Minneapolis and a staff writer for the Minnesota Real Estate Journal in Bloomington from 1993 to 1997. Earlier, he was a stringer with the Milwaukee Journal and the Milwaukee Sentinel in Madison, Wis.

He holds a bachelor of arts from the University of Wisconsin and resides in Brooklyn, NY.

More importantly, Peter is a newly-minted father, which should give him more practice in prolonged sleep deprivation needed for his blogging.

He will begin at ATD on Oct. 27.

Along with Walt and me, Peter joins senior news editor John Paczkowski, author of the rocking Digital Daily column, who formerly wrote the award-winning blog, “Good Morning Silicon Valley” at the San Jose Mercury News, and Wall Street Journal reporter Katherine Boehret, who writes the most excellent weekly Mossberg Solution column.

We hope you are as thrilled as we are that Peter is coming soon to the ATD site.

(And if you want a little taste of Peter’s work, here’s a post he did yesterday on an appearance by Time Warner’s Jeff Bewkes at the Goldman Sachs media conference and another on Rupert Murdoch of News Corp. [News Corp. is the owner of Dow Jones and of this Web site].)

The shaggy Brett Erlich perfectly reviews the sites for the Web 2.0 crowd, making fun of WSJ.com’s soothing video intro music, and the online video stars on Forbes and Fortune (one of whom, Fortune Editor-in-Chief Andy Serwer is an old classmate of mine, in fact).

The best bit is his take on the “Information Highway Traffic Jam” at the end among all us MSM types, driving like teens gone wild on the digital freeway.

Here’s the video:

BoomTown was one of the tech writers on the panel, which was talking about what the big trends in tech in 2007 were and what they would be in 2008. The others were: Victoria Barret of Forbes, CNBC’s Jim Goldman, Business Week’s Rob Hof, The Wall Street Journal’s Don Clark and Robert Scoble of Scobleizer. (USA Today’s Jon Swartz could not attend.)

Venture capitalist Ann Winblad moderated the event.

Here is the whole thing:

And here is my video of the event too (and here is the post):

(I still am having problems with the Brightcove player, so I uploaded the video to YouTube.)

Last night, the Public Relations Society of America’s Silicon Valley chapter held its annual “Media Influencer” dinner at the Computer History Museum, which featured a spate of tech journalists pitching a large room full of PR people about what’s hot in the sector.

Turning the tables this year–and apparently getting “honored” by the group–were: Victoria Barret of Forbes, CNBC’s Jim Goldman, Business Week’s Rob Hof, The Wall Street Journal’s Don Clark, Robert Scoble of Scobleizer and BoomTown. (USA Today’s Jon Swartz could not attend.)

Venture capitalist Ann Winblad moderated the event, which seemed akin to trying to herd cats.

Some of the topics included: Facebook (of course, and whose PR head Brandee Barker appears in the video below after a harrowing day handling Lesley Stahl of “60 Minutes,” which is doing a piece on the social-networking site with an apparent focus on–also, of course–privacy); the impact of the possibly looming recession on tech; Apple’s iPhone (of course, of course); Google (triple of course); the resurgence of the enterprise space; and the fate of Yahoo.

Here is video of the event:

(I still am having problems with the Brightcove player, so I uploaded the video to YouTube.)

In a front page article Sunday, New York Times writer Gary Rivlin drags out that old Silicon Valley chestnut about how hard it to is be just a plain old millionaire when everyone else around you has all those hundreds of millions and–worse!–billions.

I always enjoy Rivlin’s work and even spent a lovely few weeks with him and also Po Bronson on a lecture/debate scheme hatched by our Random House editor called the “Bleeding Edge” book tour in the summer 1999. (Here’s a quick recap: I thought the Internet was underhyped at the time and Rivlin did not, while Bronson dreamily sold more books than both of us combined.)

But it’s a bit of a stretch to imagine anyone–even in the gold rush days of the Web–not being happy with several million in the bank.

Notes Rivlin: “…Those with a few million dollars often see their accumulated wealth as puny, a reflection of their modest status in the new Gilded Age, when hundreds of thousands of people have accumulated much vaster fortunes…”

Oh, good heavens.

But Rivlin did manage to get his interview subjects to say appalling things, such as calling tech work the “Silicon Valley salt mines” (um, the food is a bit better and there are no whips and chains I have ever seen except by personal preference).

My personal favorite was a quote from Match.com founder Gary Kremen, who apparently without irony declared, “You’re nobody here at $10 million.”

At this, I can only quote the poet Emily Dickinson:

I’m nobody! Who are you?
Are you nobody, too?
Then there’s a pair of us–don’t tell!
They’d banish us, you know!

How dreary to be somebody!
How public, like a frog.
To tell your name the livelong day
To an admiring bog!”

SPOILER ALERT! HARRY POTTER IS FAKE STEVE JOBS!

Speaking of nobody we knew until just now–the Times’ Brad Stone also managed to finally out the creator of the popular Fake Steve Jobs blog. As it turns out, it is not our own John Paczkowski, but Daniel Lyons (pictured here), a senior editor at Forbes magazine.

While some will care more than others about Stone’s identifying the snarkaholic FSJ (Owen, stop crying now), it’s, of course, about the need to sell a book. In this case, Lyons’s “Options: The Secret Life of Steve Jobs, a Parody,” coming out in the fall.

In a post Sunday, Lyons asked for suggestions for a new verb for Stone’s first name, and then suggested himself: “To bust a fellow filthy hack without mercy and spoil the fun for everyone, in a quest for personal aggrandizement.”

Yes, just like Harry Potter spoilers on the Web! In fact, the Harry-Potter-as-middle-aged-man-looking Lyons would know all about that kind of thing.

MEMO TO MITT: THE KIDS LOVE BOTH SNOWMEN AND THE WEB

And Mitt Romney needs to get over himself, after he viciously attacked the snowman named Billiam. The frozen questioner was posing a pretty good question about global warming in the YouTube/CNN presidential debates recently completed with Democratic presidential candidates.

The GOP wannabes were supposed to do the digital debate in September. But that has been stymied so far when the former Massachusetts governor said a video question from a snowman was undignified, noting, “I don’t know that it makes sense to have people running for president answering questions posed by snowmen.”

Given snowmen have the most to suffer from the climate heating up, I say: Who better!?!

In all seriousness, the Jon-Stewart-tone of the Web is something all the candidates had better get used to. In fact, years hence, queries from snowmen are going to look tame by comparison.

Here’s a Dow Jones Online video on the topic with the chilly question from Billiam:
