If you provide news or documentary support for your local community and you happen to be in the D.C. area on October 28, 2010 you might want to stop by the Community News Caucus.
I don't think this is blogger/vlogger specific but it reads like all are welcomed.
The meet-up is free
Here are the details:
Community News Caucus
635 Massachusetts Ave. NW - NPR Headquarters
Time: from 5:30 p.m. to 7:30 p.m.
