Will, I wil lstart by echoing the other comments - great article.
My comment is an opinion on the influence score and the "klout" some give to it. I think it is more important to look at the score from a ballpark view rather than an individual play. For example, Joe's score is 54 and Sue's is 57. Does that mean that she should get the "Social Media Job" over Joe? I don't think so. HOWEVER....if Sue's score is 57 and Joe's is 14....well, you get my point.
