I was immensely impressed by both Barack and his wife Michelle in their interview with Steve Kroft. By far two of the strongest most eloquent people I've heard run for president in a long time.
Obama's campaign released a new social networking site alongside their campaign website called "My Obama.com." Its a good start and is definitely the closest to any Web 2.o standard than any other candidate but I think Howard Dean set an unrealistic bar when it came to internet ingenuity for a political campaign. Barack's tech team is certainly nipping at Dean's legacy though.
