Just for comparison’s sake.
The old design (click for bigger):
The new design. (Well, obviously, this is what you’re LOOKING at, but I figure this makes for good record-keeping for any future changes I might make, so…)
A friend and I were just chatting about how much more “open” the new design feels, but I find it hard to pinpoint WHY. Sure, the background color is lighter, and the Navbar/Tabs are light gray instead of blue, but otherwise, it looks awfully similar, just with the sidebar on the right … And yet, it FEELS so much more open.
Why do you suppose that is?
