Same reason why we are still using Microsoft products. We're to f'n lazy to build it ourselves. And I don't mean develop it because obviously any developer worth their salt could replicate the code for twitter in your favorite language. I mean BUILD it. Community, Scaling, Developer base, etc...

Also in a nice piece of irony, I went to make a comment by signing into my twitter account (which really just gives posterous.com access to my account BOOO!) and I got the fail whale. Henceforth sealing the deal for this guys douche baggery!
