Well, just because you're a celebrity doesn't mean you can't fail. You just fail bigger.
As for the technology, we've seen how cheap and reproducible that is. News.yc, Reddit, Digg, Netscape, and dozens of other sites have technology that probably beats that of Truemors. So the company isn't worth buying for that.
Some companies get bought for their employees. Well, Guy's "1.5" employees, if he's talking about a full-timer and part-timer other than himself, aren't visionaries, they're just people who can turn around one of Guy's ideas. Come to think of it, that makes them better potential hires for a big company than most headstrong, visionary startuppers.
So Guy just spent $12k making himself feel good. By doing so, he demonstrated how detached he is from the real world -- which, psychologically speaking, is a fine way to live. If you're like Guy and you can afford to blow $12,000 doing it.
