One of the things that we’re really excited about with Tweetree is being able to show additional information for links beyond just their title and URL.  Up until now, we’ve done this by choosing popular sites that people link to, such as Twitpic, YouTube, or FriendFeed, and adding support for their pages.

But this doesn’t have to be one-way.  Dave Winer has started discussing a mechanism for web pages to include information on what a thumbnail for the page should be.  This is in the form of a simple line you can add to any page on your site.  For example, if you link to any page on Flickrfan, such as this one on Tweetree you’ll see a thumbnail of the image embedded below the message.

We’re currently supporting this for any site that adds a tag like this one to the head of their pages:
