A new resource for sources

Help a Reporter is a new service from Peter Shankman, who says:

This list was originally conceived on Facebook, but since Facebook caps group emails at 1,200 people, this is the next incarnation.
I built this list because a lot of my friends are reporters, and they call me all the time for sources. Rather than go through my contact lists each time, I figured I could push the requests out to people who actually have something to say.

Shankman's site asks people to sign up who have information that can help on a story.
Ryan Sholin points to the service, as well as the Times' Shifting Careers blog.
