So, Ask Ubuntu just got a facelift/new theme. It's the Stack Exchange site I frequent the most. Also, recently, I have been looking for some work.
The top bar moving in to the left bar to maximize front and center real-estate on screen is good. I don't like it, but I can recognize what it's doing and give it a pass, because I'm just not used to it yet.
The thing that threw me a little was that the footer is still so large. Why would that be relevant? Because it seems like a weird divergence. I can accept that we want it all on the screen in the densest format all the time, but then wouldn't you want to slam the footer in to the left bar?
From a usability perspective, I like the job postings and being able to get there from the footer. However, I find myself just opening stackoverflow.com to open it from the right hand side-pane to get there. It would seem more efficient to put the footer in all that empty space in the left-hand side pane if we're trying to get it all on one screen.
