Well, here’s a good reason not to write off Joost quite yet: When the London-based company officially debuts its new Web-based service in mid-October, it will have some pretty hot content with its half-dozen seasons of the former NBC hit, “Friends.”

Also, there will finally be no more irksome plug-ins.

In other words, anyone with an Internet connection can watch streaming television shows and movies on Joost, with advertising embedded in various forms.

There will also be social-networking elements–you can see what your friends watch and form groups, make comments with cool tools and the rest of that sort of thing.

While all this is not going to make up for the lost time the online video service has wasted with its annoying P2P-based desktop client download, going to a Web-based, all-Flash service with more robust content is certainly the right way to stop rival service Hulu from continuing to clean Joost’s clock.

Joost was first out of the gate last year with a giant slug of funding, fancy founders (Janus Friis and Niklas Zennström, who were also founders of Web phenoms Skype and Kazaa) and blue-chip investors (Sequoia Capital, Index Ventures, as well as CBS, Viacom and wealthy Hong Kong investor Li Ka-shing).

In any case, Hulu quickly grabbed the lead in terms of press praise (I ate my words even!), ease-of-use and, most importantly, user numbers.

In the most recent stats, for example, Hulu had more than 100 million monthly video streams and 3.3 million unique monthly visitors. (But since Joost has just soft-launched its new Web-only service, it’s hard to make comparisons just yet, although the competition is now clearly afoot!)

And, although it has been written off by some, I do not think it is too late for Joost.

First, it is still early in the premium online video game.

Second, success will depend on having increasing amounts of quality content. And Joost–with CBS, Warner Bros., Sony and other unusual content like anime–certainly can keep up with Hulu’s programs from its partner parents, News Corp. (News Corp. is the owner of Dow Jones and this Web site) and NBC Universal.

Lastly, despite decent consumer uptake, the business is still in its nascent popcorn-stand stage of revenue and profit generation.

And while spending too much money and having too many employees did not help Joost, it seems as though CEO Mike Volpi has finally gotten control of the start-up beast.

Thus, while in London this week, I stopped in at the offices of Joost (near the famed King’s Cross train station, where, of course–to no avail–I tried to make it through the wall at Platform 9 3/4!) to chat with Volpi about all the changes at the much-hyped company.

Here’s a longish video, in which the always-well-turned-out former Cisco exec talks about all that and more:

Here’s Part 3 of 6 of our interview with Rupert Murdoch, chairman and CEO of News Corp. (NWS) (owner of this site and the conference), conducted by me and Walt Mossberg, in which he talks about television, Hulu, copyright, YouTube, movies, Hollywood, social networking, advertising, Google and more Yahoo and Microsoft.

Here are the rest of the videos of the interview:

Yesterday, a source told me that Flixster, the fast-growing social network for movie lovers, was back in talks to be bought by Barry Diller’s InterActiveCorp.

Those IAC-Flixster rumors flew about a month ago and were entirely true.

But no deal, it seems. IAC has apparently found the price too high, according to other sources. But, said these sources, others are still in the game.

So if an acquisition deal does happen, two intelligent guesses to the possible winner for the company with 39.5 million user home pages, more than 1 billion user-generated movie ratings and a sassy motto of “Stop Watching Bad Movies”?

Blockbuster or News Corp.

(Sources said Viacom’s MTV unit gave Flixster a look too, but also thought the price too high.)

The former because the video-rental chain has been mightily trying to break into all kinds of Web markets to give it a place to sell online. Blockbuster has been struggling of late, because of its costly battles with Web sites like Netflix and the growth of video-on-demand and movie downloads via the Internet and cable. Its online subscribership is only 3.1 million.

And the latter, because such a site tucks in nicely with some of the media giant’s properties like MySpace and Rotten Tomatoes, as well as its numerous movie and television arms. (FYI, News Corp. is in the process of acquiring Dow Jones, which is the owner of this site.)

The price? I will wager $150 million in cash that had been previously bandied about, although IAC’s offer was likely much lower than that.

Pricey, yes, since Flixster only has 17 employees and was created less than two years ago. It received $2 million in funding in February from Lightspeed Venture Partners.

But its vibrant Web site is booming and is now one of the largest movie sites on the Internet. Flixster is also one of the more popular widgets on Facebook, with more than 800,000 active daily users.

While Amazon-owned IMDb (Internet Movie Database) is larger in terms of traffic, Flixster is growing much faster.

On the site, users have profiles typical of most general social networks, with a laser-focus on movies, actors, directors and movie quizzes and news. Flixster also has video content, both professional and user-generated and relies heavily on user reviews.
