The link above goes the recent page. If you go to "Popular" (http://askpg.slinkset.com/) it's sorted by the absolute count and will never degrade.
We can easily set how much (or little) time factors into the ranking, but haven't exposed it in the UI yet. We'd like to get to that soon.
It would be nice if we eventually felt like a natural fit for stuff like this, though I realize it's not totally consistent with our positioning so far. Anything other than the ranking and deceptively named menu items that makes it suboptimal?
