I really like this. Clean and simple. Would be nice if I wasn't forced to use twitter to track my blogs though. What about an equally clean and simple user dashboard?
The original use case I had in mind was to allow twitter users to write more than 140 characters. I've since drifted away from that, and a plain ol' user registration option might make a lot more sense now.
As for user dashboards, there's just this for now http://throwww.com/u/sfard
