Before TechTV (which used to be ZDTV) there was a show on MSNBC called “The Site.” It was a refreshing look at the daily tech news, and it was hosted by Soledad O’Brien, who was not a geek. But she was as smart as a geek, and a solid contributer to the show, not just a pretty talking head. She rose up the NBC ranks to host Weekend Today, as close as she could get to her idol Katie Couric’s position without Katie leaving the show. Now she’s left NBC to take on CNN’s morning show. But I bet if Katie ever leaves, she’ll be thinking hard about going back.
