The M20: Top Marketer Blogs (gamma)

Lots of thoughts swirling about measurement.  One last tweak to the methodology here; I've put together metrics of authority, attention, and influence.

• Authority:  20% Technorati Authority + 20% Google PageRank
• Attention:  10% Alexa traffic
• Influence:  50% Feed subscribers

Let me explain.

Authority:  40% of total.  Technorati scored by rank decile, Google straight up.

Attention:  users actually visiting the site.  I wanted to combine this with other ratings (e.g. NetRatings, Compete) but only Alexa measures the majority of blogs here.  I know Alexa isn't perfect...

Influence:  blog subscribers.  There aren't clear numbers on market share.  I'm using Feedburner stats from blogs that make them available and making an assumption that Bloglines subscribers are 20% of total for others.
