I don't know whether it would scale for others or not. It scales for me, but then, the krita forums remember my login, and there are only some dozen posts a day, right now. And I don't feel compelled to answer every forum post that passed by on irc. But in general, irc and rss notifications work for me. A mailing list gateway would be even better, but I don't have that. Just visiting the forum to check what's new -- no, that wouldn't work at all.
