I'm not promoting the site, though I do hang out there from time to time. It's a useful example.
I don't have a particular beef beyond noting that in some interfaces, the V shows a bit of the M, which makes one wonder about the C.
Also, anyone that insists on a strict MVC pattern should be walked from the plank of V so that they make their peace with the C. (I don't particularly care if the goal is MVC or not).
