Tom Green's show is interesting and innovative, and his celebrity interviews are better than any you'll find on a TV talk show.  Largely because the celebrities let their guard down in the low-rent facilities.<p>Conan has a couple big personal obstacles to going online.  First, he'd have to lay off a lot of his staff, because an online talk show doesn't require and can't support nearly as many crew members as The Tonight Show.<p>Second, he'd be taking a big pay cut.  If the show did well he might still have a shot at seven figures, but any TV talk show he does would probably pay him at least $15-20 million.<p>Third, he'd have fewer viewers, which could be a blow to both his ego and his cultural importance (that's not to suggest that either is currently out of whack).<p>The upside is that Conan is probably one of the best-positioned people in the world to do something like this, and he has the means and support to try it out as an experiment for a few months.  At this point in his career, though, he may not be looking to make such a big change.
