News U. and the Knight Digital Media Center are hosting a Webinar on social networks on Tuesday, April 14, 2 to 3 p.m. EDT.

The Webinar, called Social Networks: The New Architecture of the Web will help decode what’s happening on social network giants like Facebook and Twitter as well as specialty groups and how.

The Webinar will be led by Paul Gillin, a well-known social media expert and newspaper industry analyst who blogs at NewspaperDeathWatch.com. Note: I’ve interviewed Gillin for WordCount and he knows his stuff. The cost is $24.95.

Although the information sounds like it’s primarily aimed at journalists working for MSM, it could be worth looking into for new freelance markets or if you’re contemplating starting your own social networking-based new media venture. Register or learn more here.
