For the past several days, I noticed that the interface around my Facebook account has been a little different, and I assumed that they were rolling out changes to everyone. It looks like that is not entirely the case, based on stories like this that have showed up on my Techmeme feed. Apparently I am part of a limited group of Facebook users that is testing the system (and without my knowledge until now). Overall, I generally don’t mind the changes, though I wish there was a way to collapse the posting panel after you click the button to expand it. The screenshot below shows my News Feed using the new interface.
