The comment stream at the bottom of each page (when you are logged in) is good, but only gives titles of forum posts which rarely tell you the conversation (forum thread) they are part of. The illustration below indicates the way the first couple of words of the thread title could be incorporated into the current design, giving useful context. Left is current comment stream, right is proposed improvement.
Given the small amount of white space under each title, perhaps two lines of text could be used, consistent with the how the 'latest contributions' incorporates a fade/transparency...
Would it, also, be good to break forum topic replies from the rest of the comments? They aren't really comments in the sense of the term (even though we use the comment module).
