You could probably start with a plugin that uses the tweetmeme API - http://help.tweetmeme.com/2009/04/07/api-documentation/ http://help.tweetmeme.com/2009/04/07/api-documentation/ - it'd give you url count, comment count and date created. -- the other direction you could go in, is start tracking everything a person shares, bookmarks and likes on all their social networks, and aggregate that into a person's public profile. (unfortunately friendfeed doesn't give such info on a url like tweetmeme) From there, use that information for the plugin above, when assessing a url.
