I took a look around, and despite you saying you're more of a designer than coder, it works pretty well for what you have to do.

Less words on front page might help. I was curious about how you were going to have a different style of conversation, but after looking around for a bit, it seems like, as you said, a tumblelog and friend feed.

As an aside, I liked the parens in the menus, as it gives it a different look.
