Are you a Seattle-based nonprofit using the social web for social change, or a company that has a cool new social web product that nonprofits could use, or an innovator who has an idea for a new social web tool that you want to try out on a "do-good" audience?

We've got a gig for you.  Seattle's Net Tuesday is looking for speakers.  Net Tuesdays are monthly meetups across the country of social changemakers and web innovators who get together to network and share resources about how nonprofits can use the social web for social change.

We're excited to announce two new confirmed plenary speakers at the upcoming NetSquared conference: Michael Turk, Vice President for the Industry Grassroots for the National Cable & Telecommunications Association, and Dan'l Lewin, corporate vice president of Strategic and Emerging Business Development at Microsoft.
