It's one thing for CNN talk-show host Larry King to ask Bill Gates or Eric Schmidt whether they think the internet is a "viable" political medium. It's another for him to pose this question (as he did on last night's show) to Roseanne Barr and act as though he expects a serious and thoughtful response.
What makes a standup comedian-actress an expert on this topic? Nothing, so far as I can see.
I don't dislike Roseanne Barr. I just don't get why she's treated like she has such insights on the power of political discourse on the internet.
