We have a tab to sort Popular Posts, based on favorites. I would find use in a Most & Least Active tab (each side of that for different reasons), based on number of comments.
Can we have a Popular Comments tab like the Popular Favorites one? [more inside]
There is a single page that globally ranks comments across the three sites by number of times favorited, spanning the past seven days (link). There are individual pages that rank posts for each subsite by number of times favorited in the past day (AskMefi, Mefi, and Meta). Do there exist individual pages for each subsite that rank the comments most favorited within the past 24 hours — or even a single page that spans all three but ranks the most favorited comments in the last 24 hours?
