I posted a couple of forum topics a while ago and just logged in to see that someone had replied. I was pretty surprised that I didn't get emailed about the reply and even more surprised when I asked in #drupal and apparently it's not possible to subscribe to a forum topic. I think this is assumed behavior these days and should definitely be supported.
Example: When someone replies to http://drupal.org/node/183006 everyone who has touched the thread should get emailed (or be able to opt in at least).

tvn commentedClosing old issues. This conversation should be a part of a larger 'improved notifications system' discussion anyway.
