First of all I would like to say, I love your community on Google+ with Danny Brown, great insights into influence marketing and I'm on your side. I've pre-ordered the book too.
I believe influence can't be monitored by a score and I for one, don't want to be associated with a number either.
What I can say, is the infographic was fun to do, my first one and I have learned a lot from doing it.
To be monitored by just twitter influence and blogger outreach is no way an acurate influence score online as I would say I have more influence on other channels than twitter and even my blog for instance but when this report was made it clearly stated how the score was made.
You have a great insight into this, but what it does for others is it encourages them to do more or do better, so for that I'm happy to sift through the lists to see if I can find any encouragement and seek out better ways.
Thanks Sam, can't wait for the book to land in my letterbox.
