Who are these Grassroots All-Stars?

by Chris Healy [courtesy of Blog for America]

There are a lot of candidates for DFA's Grassroots All-Stars, which I'm taking as a very good sign! I don't know many of them though, and would appreciate others' insight to help figure out who I should investigate further.

Who do you recommend from this list of potential Grassroots All-Stars?

 Thanks!
