We've had a number of developers ask us if there whether there is an official MySpace Developer Platform IRC channel.  Right now there isn't, however that hasn't prevented a couple of developers from taking the initiative and creating their own:

irc://irc.freenode.net #myspacedev

This is not an official MySpace channel, but developers are of course more than welcome to hang out here to share ideas and advice.  Of course we'll try and pop by when we can too.

If you don't have an IRC client, you should check out the page on Wikipedia. I tend to use Chatzilla on my Firefox install and Colloquy on my Mac. Stephanie swears by Pirch.
