According to this guy, and Technorati, this calculator creates a ‘value’ on your blog. 

I assume its related to Technorati ranking and credibility, and maybe amount of content… 

Apparently my impressive and high profile blog (not) is worth $564.00, looks like its time to retire people!

What do you think? Load of wallop or is there some kind of logic to it?
