WordPress and Twitter connecting up

  In a comment posted here earlier today, Matt Mullenweg says that they're working with Twitter on a way for WordPress blog posts to appear inside Twitter.
    "Posts on WordPress that use the wp.me shortener are now being embedded on Twitter, we'll show a photo if it's a photo post, or an excerpt if it's a longer blog post, still experimenting on the best formats."
  This really should be a protocol that anyone can hook into, on either side.
  If that's the way it's going, I'd like to get a look at it before it's frozen, to help make sure we're not repeating mistakes of the past. It would be a good idea to let other people at least look at what you're doing.
  Matt, your product has benefited from lots of open development. Here's a chance to put something back.
