Last week my colleague, Amanda Lenhart, appeared on the Kojo Nnamdi show to talk about the opportunities and hazards that come with using social networking sites.

The show, which features data from our most recent report on social networking, is archived and available here.

And on Wednesday I had the pleasure of appearing on WHHY’s “Radio Times” show with Marty Moss-Coane to talk about the evolution of social networking sites and their maturing audience.

Wednesday’s segment, which also features thoughtful commentary from Time tech columnist Lev Grossman is archived and available here.
