Me.dium had a release over the weekend – if you are a Me.dium user make sure you get the latest Firefox plugin. If you aren’t a Me.dium user, feel free to bypass the private beta by using my magic invite code.
Phil Butler at Mashable has a nice blog post on the update. There are plenty of under-the-hood changes – especially around performance and scalability (the really hard mysterious stuff), but there are a bunch of neat UI enhancements on the Firefox plugin (including one that I really wanted – moving my logged in friends to the top of the friends list.)
