Blogarithmics: How Do We Measure Blogs?

I've been thinking a lot lately about how we can measure blog efforts for our customers. I recall a thought shared last year by Mary Hodder on this subject, but did someone find a measurement?

I'd like to analyze the efforts of our customers using the following items in a weighted formula (listed randomly here):

• Number of posts
• Number of incoming comments
• Number of author's comments elsewhere
• Technorati rank
• Alexa Rank
• Google Page Rank
• MyBlogLog community additions
• Outbound Links
• Outbound Clickthrough
• Incoming Referral Links from blogs
• Incoming Referral Links from search engines
• Feed Subscribers
• Feed Reach
• Feed Clickthrough

There are probably other items (del.icio.us history, digg/reddit/stumble/etc. links, what else?). Maybe we need a sabermetrician here.

If there's a tool or conversation about this, let me know. If not, let's start one.
