The new changes here seem to have ignored some of the biggest issues that make visiting this site a chore. I worry that you've boxed yourself in with the platform and can't fix most of them, or have decided that they are good ideas (the grid layout of communities is one example that seems destined to stay).
But surely you can fix the design to be less wasteful of screen space. This is a shot from a large desktop monitor. The green highlight is actual content. The yellow is everything else, much of it wasted space for no good reason.
