I know Dan is reachable, but I always feel like I should not bother the man. He is currently working on 10 things, among them an AI, a distributed AI.

If I had one constructive criticism to give to Dan it would be this: Release stuff, it wont be perfect, that's ok.

I suspect he's only holding back because it can always be "a little better" - Good being the enemy of perfect type of thing.
