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.
There is a LogBot called WhatBot running on the channel. See http://whatbot.charlvn.za.net/ for a list of all the logs available. Please contact Charl van Niekerk if you have any questions or problems with this bot.
