Wondering what the heck a PublicMediaCamp is? The next National Center for Media Engagement can help out with that. Its next Peer Webinar, at 2 p.m. Eastern this Wednesday, is "PubCamp 101." Presenting will be Jonathan Coffman, PBS's product manager, social media; and Peter Corbett, an event expert and CEO of iStrategyLabs. They'll cover the history of PubCamps, why PBS and NPR are involved, and how to create a local PubCamp. Sign up here.
