Most recent comments (suggestion)
I think it'd be cool to have a way to see the most recent comments on exercise questions. I'm not sure how difficult this would be to do, but if it's feasible I think it would be really beneficial to both people who have specific questions on an exercise, and people who want to help.
I really like your idea. I had a question about one earlier and it had 205 comments (it had gone off on a tangent about something) and I didn't even bother to look through so I didn't ask. I've forgot what it was now so it can't have been that important.
