First off I wish Twitter had this. I suggested it but it was never added to a feature. It's a Miceoblog APP like twitter but with the a difference: 1. The ability to have two sections of your updates. First is your public updates, and the second part is the protected updates. Only the followers can view your protected updates. 2. Tags Seperated by commas for user names. 3. RSS Aggregation related features. Jaiku used to have that feature but they disabled it when they opened registrations. So anyways, I just keep on dreaming.
