So I finally joined twitter to see what all the fuss was about. And in the time it took me to upload an avatar and fill out my profile (with form posts approaching a minute), I’ve read a blog post about a recent DB crash, and got a ‘too many tweets’error when loading the home page. Mind you, its 1 am EST.
Oh this is going to be good. 
It took over an hour for twitter to stabilize and let me start posting updates. but now that I can use it, I can see the appeal.
Still like the way pownce segregates the content into types, but there is more of a conversational element to twitter.
