It's no secret that Twitter is popular. A quick look at the race between Ashton Kutcher and CNN confirms the fact that Twitter has broken out from its geek status into something larger. But why? And more to the point, why do writers and journalists feel the love for all things Twitter? We ask web veterans Marshall Kirkpatrick, from ReadWriteWeb, and Christina Warren from Download Squad. While no one can be certain, Marshall thinks it has something to do with Twitter's robust structure, which lets any developer with virtually any idea piggyback on top of the service and add their own unique twist. While the company is busy keeping the service growing through all the incoming users, outside developers are the ones adding all the new features. Christina feels similarly, but also thinks that once people get past the intial shock of using something that amounts to opt-in stalking, the users are prone to actually enjoy sharing events in each others lives. What do you think? Why is Twitter so popular, and will people still gravitate toward it even with bigger players in the space like Facebook and MySpace?
