I have noticed that posts from Seesmic & TripIt often aggregate & show a the app description + icon. Here's a screenshot (couldn't attach, < 10 points)

I'm posting messages to a users wall with the Graph API, but I'd like to know how to make the app description show up.
I have also tried posting a few feed stories successively but they are not aggregated like in the screenshot. Any ideas how to do this?
Thanks!
