haven't logged in. few things that didn't make me login: no screenshots/preview. Although there is a demo video, I won't be able to watch this at work.

No Privacy policy listed - how safe is my data? how secure is my data?

Also, you could connect using facebook and twitter, but you have your blog link just beside - confusing me that you could connect thru posterous (send emails?)

ps: could you tell us what stack/framework are you using? Is it on a VPS or shared host?
