If we take it private* (password required), it could serve as a great adjunct to the teamd newsgroups. For example, if you attach, say, 10 or 20 images to a post, it automatically makes an ajax gallery out of them. Posting via email is as simple as having your email address authorized and sending an email to post@posterous. There is more and they are adding more all the time. And for Mart, there is the truly wonderful PicPosterous iPhone app. ;)

*I have to look into the effect that would have on the autoposting to twitter.
