Matt - I have a posterous site (which uses a subdomain of my main site) that I mostly use to index some of my favorite articles - same purpose as delicious but I can rest assured that the content will always be there. Since most of the site has dupe content, it may lose the PR (which I dont care for) but will that affect my primary site ranking.

I am not sure if Posterous offers the ability to add a robots.txt file with which I can tell search engines to exclude it, but would that prevent my primary site ranking from being affected?
