The Freenode IRC network has a channel called #whatwg where some of the more active WHATWG community members hang out. Feel free to join us!
If you want to run a bot, let us know. If they are useful, e.g. providing logging facilities or watching the Subversion repository, then they are more than welcome.
http://krijnhoetmer.nl/irc-logs/ has the logs for #whatwg.
