I was going to call this The Kiss of the Spider Blogger but I think I need to move on from movie title puns as head lines.
Anyhow, the issue of how "influence" and "fame" are not the same thing is shown well by this analysis by Flemming at Onalytica.

So over here at Bell Pottinger we have added a rather nifty new feature to our webmap doodah whereby you can toggle between the "fame view" and the "influence view".
