Hubot vs. Pagerbot

Hubot is a chat bot, modeled after GitHub's Campfire bot, hubot. He's pretty cool. He's extendable with old community scripts, or new community org and your own custom scripts, and can work on many different chat services.

Pagerbot is a bot that makes managing PagerDuty on-call schedules easier. It currently supports IRC and slack, and can be easily deployed to heroku.
