Twitblogs

Twitblogs is targeted towards Twitter users who want to write more than 140 characters, or want to embed images into their posts, etc.

Users actually don’t even create accounts. Instead they log in with their Twitter credentials.

This is what's mentioned at TechCrunch.com. It seems like an interesting move forward but critics wonder what S. Sethi (owner of twitblogs.com) will do with users' data. Mind you, Bubbl.us faced similar criticisms.
