I went last year and helped out a bit. (I designed the logo for one) It was fun even for a non-scientist like myself. I really dug it because its a good sized home grown blogging event. Even though its a NC event people from ALL OVER the world attend. If you publish in scientific journals you need to be at this event. Check out the program to get the details. Also read what other bloggers and media had to say about last years event.
