There are two sites out their that appraise the value of your blog, one of which is powered by technorati, which measures how much people are linked to you and how many visitors you get. The other site is from LeapFish, which measures the value of your domain, and how many search sites indexed your site like google, yahoo, msn, etc. I measured with both services. With technorati my blog is worth absolutely nothing! However with LeapFish my site is measured to be worth about $2904. I would accept anything in between that.
