Someone already commented on the new comment icon, I don't know if it is possible but it would be nice if there was a way to tell if some of the sticky posts were "updated" and differentiate this action from "new" comments in that thread. Such as in the recruiting thread. Make sense?

I guess they say updated on the thread titles, but it would still be nice to know if it was actually edited in some way... Just a thought. Nice Job!

This one may be a bit difficult. In the topic list view, the icons are relevant to that entire thread so would an icon that is denoting an edit has occurred appear when any single post within the entire thread has been edited? If so, how does one find the exact post that was revised? Also, which icon would override the other if someone makes a new post to that thread?

The guys that started the recruiting threads have been pretty good to add the "(updated date)" to the Subject line for this very purpose. If they forget, you can also check if a post has been edited by looking at the bottom of the post. It states the last time the post was edited, by whom it was edited, and how many total times the post has been edited. It looks like this example taken from the bottom of the first post in the 2014 recruiting thread:
