We recently noticed a post on the Data API Discussion list in which Philipp Kewisch started an unofficial Google APIs IRC channel (network: irc.freenode.net, channel: ##google-apis):
"I was working on a program that uses the Google Calendar API and thought it would be great if there was a channel that could answer my small questions quicker than the groups. I myself can offer some insight into raw protocol usage in some languages, javascript, php, and probably a bit of perl - all focused on the Google Calendar API."
We won't be staffing the channel ourselves, but we're really excited to see Google API developers helping each other!
