Discussion of ShoeBot primarily happens on our mailing list:

• Sign up to the mailing list
• Read the mailing list archives, either at GMane? or Nabble (recommended) or the Mailman originals.

We have IRC discussions on #shoebot on FreeNode, feel free to drop by anytime! (Although posting on the mailing list to let other know you'll be active on IRC may be a good idea as the channel isn't always active)

Also, Ricardo maintains a microblog where you can see comments on how the official codebase is progressing: http://identi.ca/shoebot
