We recently revamped our Net Tuesday page on the site so that each of
the Net Tuesday locations (SF, Houston, Washington DC--we're still working on Chicago's page) has its own page where they can add content.
On the SF Net Tuesday page you can download PowerPoint presentations given by Kiva and PLoS at previous Net Tuesdays, as well as audio recordings of the presentations, and interviews with the presenters by David Collin.
If you'd like to start a NetSquared Meetup group in your area, download a Net Tuesday toolkit and let us know at net2 AT techsoup DOT org. We're still looking for someone to take over the NetSquared Los Angeles. It already has 49 members who are just waiting for an organizer.
