It's still early days for us but we're seeing pretty good engagement and retention. Even though people sometimes describe it in terms of Twitter, I actually think its something very different. Subjot is more a discussion and conversation platform and I think its more accurately described as a new kind of forum (its topical and has comments).

So as Subjot's cofounder, I still love Twitter and plan to continue to use it to broadcast my thoughts... particularly ones I'm not looking to have a conversation about.
