FriendFeed Blog: Simple Update Protocol. FriendFeed infamously poll RSS feeds on the 43 services they support millions of times an hour in an effort to keep their content as real-time as possible. SUP is a new proposal by FriendFeed for a sort of “master feed” of changes to a site—instead of hitting the Flickr feed for each of their users they would just poll Flickr’s SUP feed every minute or so to find out who had uploaded a new photo, and only retrieve the RSS feed for those users. # 28th August 2008, 12:16 pm
