I’m part of the Facebook redesign?

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┬áhave 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.
