Somehow a buggy, little web application has become the favorite locale for Internet aficionados worldwide. At first it was cute--the fail whale carried off by the Twitter birdies, over capacity, bringing back that beat. But this irritatingly simple application as achieved a sort of market penetration that most companies would lie, cheat and steal for--Twitter has users that create applications to make it better, that evangelize and convert the nonbelievers.
Every time a Twitter fan's handle gets shut down (happened to me, @tibbon and others last weekend), every time a person's followers spontaneously disappear (reported two or three weeks ago), the Twitterati start to wonder how long it would take to rebuild their network of people elsewhere.
Don't you see Twitter? You're the platform of choice for the conversation, but we'll do what we please with the relationships.
