This post discusses a bit Conan O'Bien did on his second night in the new late night spot he took over from Jay Leno. The article discusses Conan's negative take on Twitter and how he thinks its a lame tool for celebrities to promote themselves and boost their egos. While this is a comedy based show the blogger was concerned that Conan was going in a bad direction with this. Because it is a late-night show Conan does have to appeal to an older market, so his aversion to social networking systems like Twitter does make sense. But he should be careful not to alienate the younger crowd that truly are the majority target audience.
