If you begin to hang around social media types who are trying to understand the dynamics of social media, influencers and influence get mentioned a lot, as do nodes. This is particularly so discussions lean towards social media’s role within the marketing, advertising and PR mix. (On which note see the slide show by John V Wiltshire in last week’s recommended reads)

So I was interested to read this post by Anthony Mayfield entitled “How advertising distorts brand marketing” and his corresponding slide show (below).

My summary: influence can be a flighty thing.

Anthony also pointed me in the direction of friend Alan Patrick’s site (always nice when that happens), and his outlining of two reports that have recently come out about Twitter and influence, which is also worth your attention if you’re fed up of the LOTS OF FOLLOWERS = LOTS OF INFLUENCE mentality.

And, by, the by, when it comes to measuring influence on Twitter a combination of the tools Twitalyzer and Twitter Grader will probably give you a good a picture as any for free.
