Here we go with Round 2. Great reactions to the alpha version of the M20 list! The best part – new marketing voices are being highlighted in social media, getting beyond the "echo chamber" that exists in this space. (Another great aspect is the addition of many non-U.S. blogs to the list.)
This is also why I’ve tweaked the rankings. I believe that the rankings should be totally transparent, so anyone knows where they stand at any time. I also believe that rankings should reflect BOTH authority and influence. I’ll explain more about this after the list, because talking about it is kind of like watching sausage being made.

Technorati authority has been replaced by a composite score: 50% authority + 50% influence. This breaks down as:
- 30% Technorati authority, by rank on list according to decile
- 20% Google page rank
- 50% Bloglines subscribers, by rank on list according to decile
The highest Technorati rank in the list is Todd And at 717; so any blog between 645 and 717 gets a 10, or 30 points. Google pagerank is used directly; the highest page rank in the list is Eric Kintz at 7 (i.e. 14 points). Bloglines subscribers are cut by decile as well. John Porcaro is highest at 372; so any blog with 335 to 372 subscribers gets a 10, or 50 points.
The number of links to a site measures authority. But authority can also be gamed through blog tag and other memes. Thus Google page rank completes the authority metric being a tool in use by the general population. I considered two other sources; Compete does not measure subdomains and Alexa comes up as spyware for many people.
But links along aren’t enough. There’s something to be said about the number of people subscribed to a blog’s feed. Engaged? Maybe. Maybe not. But subscribers mean influence of ideas. I don’t think that the number of Bloglines subscribers is a perfect metric by any means. For example, the number of Google-related subscribers to this blog is more than 2x Bloglines on any given day. However, Google numbers aren’t publicly available, not everyone burns a feed through Feedburner (and has publicity turned on), and Bloglines is the only reader where you can see everyone’s stats. Perfect? No. But it’s the best of what’s around.
As always, your suggestions on additional blogs, as well as better ways to measure authority and influence, are greatly appreciated.
Next update (gamma or live) in two weeks.
