I really like this layout. The added whitespace and clear focus on the content (by having a different background color for the sidebar) is very effective.<p>I think I'd put a bit more space between the Name+Picture+#ofVotes and the content - perhaps half the space you have between paragraphs? I'm not much of a web designer, though.<p>One important factor is that there's no Quora branding - I'm sure that would be a prerequisite before they would consider the layout.
I have seen many of my friends and colleagues use Quora alot. And I like their concept. But some how I don't feel like visiting because of their UI. I wish it was little easier to read / skim. May be it's just me.<p>I was playing around with their CSS. Wanted to know your opinion / feedback.
