How much is my blog worth?

Some domain fetches lots of $$$. I came across a site which calculates how much your blog is worth. Please don't ask me what the calculation is based on, or how it is calculated. I tried input popular websites into it and got these values:

www.yahoo.com $11,662,267.32
www.google.com $80,904,791.94
www.microsoft.com $28,417,249.98
www.bbc.co.uk $22,289,732.82
www.friendster.com $11,693,317.02

You can try out and see how much your blog is worth too. The link is provided on the side bar. Do let me know how much your blog is worth. On furthur tries, I found these:

www.brudirect.com $0.00
www.qipswimming.blogspot.com $0.00

My conclusion is, no matter how many people visit your site daily, it's not worth a cent.
