Suggestion: Auto-follow replied to discussions

[Troy Fisher]

As the site continues to grow it can be more difficult to follow conversations, and I almost always forget to "follow" the conversation, most forums auto-follow after you reply.  Or perhaps it could be an option we could set, I can't imagine some of our 14k reply people auto-following but it could drive more involvement in threads that haven't creeped up to that hot topic spot.
