I was going to post that this new design change will cause a massive user backlash (ala News Feed), but then I realized they're doing it during the summer when many people are on vacation/busy and have less time to actively complain to their friends.
I think we'll see some serious complaining, but not as much as the News Feed changes which caused a "Face-stalker" uproar.
What's hilarious is that since they've changed their look & feel, they can't justify that lawsuit against that German social network anymore, heh.
