IRC users and people who should really be working may be glad to know that there is now a dedicated channel on irc.freenode.net called #accessibility.
The channel is already frequented by several WAI members and you will also find me there most of the day (timr), for you to pose your questions and comments on web accessibility related matters.
If you dont fancy lurking, or you want to see what goes on before you join in, the logs are posted daily at http://svg.jibbering.com/accessibility/. There is also a bot called “chumpy” who collects links posted to the site and builds an accessibilty-link-log. You can view the link-logs at http://chum.wiseguysonly.com.
