Hey David, thanks for the great article. We're working on making it useful for even pro bloggers like yourself. You could imagine emailing wordpress@posterous.com and have it go directly to your wordpress blog, or if you had a camera phone photo you wanted to post everywhere, just email post@posterous.com and it shows up on Facebook, Twitter (a la Twitpic), Tumblr, Wordpress, and your Posterous all through one easy email attachment.

Wordpress does have a little-used way of emailing in blog entries, but using an outside service is much easier to set up and use.
