Facebook is doing a partial roll-out of its new redesign this weekend.
I say "partial"; partial being 80 million people!
That sounds like a lot of guinea pigs until you consider that Facebook actually hit 400 million users this week.
The new design primarily focuses on rearranging tools; locating them to hopefully more intuitive locations.
Notifications and chat are moving from the bottom right-hand side of the screen to the upper left.
I haven't played with it myself. However, word is the photo uploader has been completely rebuilt from scratch. That sounds promising to me, since the old one was, well, ca-ca.
You can bet by Monday on two things:
1) There'll be a new Facebook group called "I want the old Facebook back".
2) Membership will be in the six digits.
