The comments view for a community shows recent comments but doesn't identify the threads that they came from, which is confusing. There is a link to the thread from one of the little icons underneath, but since the thread urls just give a numeric identifier without anything showing the thread topic, it's still difficult to see which comment came from which discussion. Example.

Also, the RSS feed for a community only gives the posts, not the recent comments. Since there is a recent-comments web view, maybe there is a simple way to connect that to RSS.
