1. Nancy, I think it is more complex. What if there are really interesting people whose posts are often filled with gems, but at the same posts some self-infatuated or status update stuff ("going for breakfast") ("sitting in my garden") stuff which is not interesting to almost all. 2. Christophe, I don't understand why you have included my name. I don't think we ever met, and you certainly don't know me. I had nothing to do with the CNN story.
