One of my concerns would be that people would then be tempted to reply to a thread simply so that they can receive email notifications upon future replies. That could reduce the signal-to-noise ratio.

Allowing people to just register themselves for when a new reply was posted, without having to reply themselves, would prevent this problem, but then there might be a scalability problem where the FlyerTalk server(s) would be burdened by having to send lots and lots of email when somebody posts a reply.
