1. When you respond to a person, that person has no idea unless they check their comment tree. Is that right? If so, why not give a notification? Make it like reddit.<p>2. There are certain topics that get brought up pretty frequently and it seems like the conversation starts from ground zero nearly every time. And this forum disables commenting after a certain period. Doesn't that just encourage starting a new thread and having the same conversation again? Some forums deal with this by making stickies.
