Worth Nothing!

I just found out according to Technorati that my blog is worth $0.00. http://bobfranquiz.typepad.com/bobfranquizcom/ blog is worth $49,114.98. How do you place value on blogs? Readership, comments, content, number of posts or just random? I'm not sure. Hopefully, I'll revalue next year (because I might need to insure my blog) and it will be at least worth $1 at that point!
