User blog:WildJackal/Why do all accounts now say, "Member Since June 25, 2011" now?

I noticed that lately EVERY single account says that we've been a member since June 25, 2011. I've looked at quite a few people's accounts today and noticed that every one of them made it look like they joined today. And I was like, "Hmmm... lots of new people comin' in, eh?" Then when I checked mine it said that I joined on June 25, 2011 also; when I've actually been a member for much longer than that. What's going on? Has anyone else noticed this?
