Mary Hodder @ Napsterization has posted a great idea: A wiki site for speakers. (What a wiki is.) From her post:
I've seeded it with about 50 women, but I want men and women to be put themselves up. The goal is to show conference organizers that when they are looking to have a panel or talk on an area that there are many folks to choose from. I will be adding more men, but this effort comes from a need we discussed at Blogher, where organizers often say they can't think of any women who are expert enough to talk, or they just chose those they could find in their usual circles.
I want to broaden the circles, get more voices out there and make more opportunities for all of us. The wiki is also an effort to make information explicit and easily edit-able by anyone, that in the past has often been locked up in Speaker Service Bureaus.
Speakers, be heard!
Many thanks to Gary for letting me know about this!
