I.e. everything goes to Facebook, but Facebook does not get duplicates of stuff. Bookmarks go to delicious, everything else goes to posterous. If I tag a posterous entry with 'fb' it goes to Facebook via Twitter. Images sent to posterous get autoposted to Flickr. Facebook then pulls them from Flickr. If I only want to status update, I use Twitter. If I want to post content, I use posterous. I am guessing that I will not be uploading stuff directly to Flickr, but I'm not sure.
