Cool site. I can definitely see myself browsing through it to learn some new stuff.<p>If you're interested, I made a few notes to try to help you improve the site:<p>* The point count on each Q&A section gives the points for the <i>question</i>, not the answer. The answer score doesn't seem to be given at all.<p>* Selecting a user/question which is low on the page doesn't change the scroll position. You need to manually move the browser up to the top of the content. For questions, this is easy to notice, but it's pretty jarring for users lower on the list, since there's no obvious suggestion that you're not at the top.<p>* If you select a question for which the users answer isn't the accepted one, nothing loads in the answer section, with no indication as to why.<p>* Your onclick hand;er is a bit overzealous. Ctrl+Clicking the SO link at the bottom of the answer closes the question on stack-ed. Same thing when selecting text. I'd suggest having explicit open/close buttons, or possibly just an explicit close.<p>* If you do add an explicit close, you may want to think about having the large question title at the top turn into a link to the question. I know that there's a small link at the bottom (see above), but I instinctively tried to (Ctrl+) click the larger link before I found the smaller one.<p>* You may want to consider allowing sorting by vote, in addition to your presently available view and answer count options.<p>* You may also want to consider making it a little more obvious that "topic" means "tag". The most popular tags are for languages, so its easy not to realize that it's not limited to just that.<p>* Deselecting all tags doesn't collapse the other portions of the page (top users, questions). This is a bit confusing when you're trying to select a new topic.<p>n.b. Ctrl+Click is the same as middle-click. On most laptops, there isn't a middle button under the trackpad, so we use Ctrl+Click instead. My laptop is like this, so I can't say whether a true middle click would make a difference, but I expect it wouldn't.
