Over at A Blog Around the Clock there are a series of posts with great video interviews from ScienceOnline2010, but I'd like to especially point your attention to this one with David Kroll and Damond Nollan, both of North Carolina Central University. It was filmed shortly after their session on "Martin Luther King, Jr., Memorial Session: Engaging underrepresented groups in online science media".
I missed this session due to a combination of sleep deprivation and headache, and am really regretting it. Isis has a good post based on her attendance at the session, however - you should read it.
You can also follow the Twitter conversation about the session with the combined tags #scio10 #mlk.
Dr. Free-Ride has posted a collection of her tweets from the session here. And a fine job she did, too.
