IRC is always where devs default to, so we have to support it.
Slack is the new standard with Gitter being pretty cool too. Our Gitter has had minimal use. Many people use and are moving to Slack as a chat platform for work. As I suggested in the Slack thread, we can possibly author/find a script that adds users to our bevry.slack.com room upon signing up at discuss.bevry.me or added when signing up from the terminal when running
docpad run for this first time (as the prompt asks them if they want to be added to the mailing list at this time as well).
