I recently installed Q&A on my site and so far it’s going good. My users have taken to using it, but many seem to treat it more as a forum and discussion section than Q&A. The problem is that the answers are sorted by points rather than in chronological order. Points based system is great for Q&A, but it can really mess up the flow of discussion.
As it is now, the follow up questions and comments can get really confusing. Say you reply or comment to an earlier answer, but someone upvotes your comment. As it is now, your comment displays above the comment you replied to. This hasn’t happened in my site much yet, but I can see this becoming a real problem once the section gets more popular.
So the Q&A plugin needs, scratch that, demands, reply to function so that replies and comments to earlier comment are displayed together. Like in Quora and other Q&A sites.
