Create a vanity roster command for a twitter list of councillors

Once upon a time, I wrote a hubot script that would rank all the members of github org by followers count. "It was fun, healthy competition!" says the guys who was third from the top.

Anyhow, I was interacting with Paul Ainslie on Twitter when I realized it might be fun to have a roster for city council. Seems that someone is already maintaining a Twitter list:

The original inspiration for my hubot script was this one, which we can probably steal and modify to use list members instead of followers:
