Twitter and Bobby Flay
It may not make sense linking twitter and Bobby Flay, the popular chef that has multiple programs on the Food Network. But, understanding the way that twitter needs to be to achieve success are.
The YES Network had a one on one interview between Michael Kay and Bobby Flay for the Centerstage program. And inside the interview, in a response to Kay asking about celebrities coming to his restraurant, mentioned that he did not care much for the celebrities coming in during big openings of his new restaurant(s). Why? Because he mentioned that he did not want his restaurant to be known as a "hot spot", and like everything in Hollywood, a hot spot is only hot for so long. He was more interested in it becoming successful the same way many other restaurants have in the past, with a good base of customers, many that are local, that can go to the place often.
That is where I think Twitter's success needs to be. The way Twitter has exploded recently (which may be the reason twitter.com has been flaky) is via the celebrity club. Twitter has become so popular and mainstream that even ESPN talks to athletes about twittering, and if they don't will they and/or why they dont. Twitter has to keep that "ground movement" of users, instead of just trying to become popular with celebrities, in order for it to succeed. If it doesn't, like many other web 2.0 startups, it has a good chance of failing.
