Good summary by Elizabeth Albrycht writing for the CEO Bloggers’ Club. She includes the following metrics:

– how do you measure the time spent reading and/or writing blogs? (billable hours?  percentage of salary?)

– are employees blogging on their own time…or company time?

– is it a group blog or a solo author? Who is managing the blog?

I would add… if a top-level exec takes on a blog, how should his or her “blogging performance” be measured? Buzz in the blogosphere? Mentions in the media? Number of sales closed as a result of sales team being able to point to the exec’s “thought leadership” blog?
