Cubestat is a free online tool which estimates the worth of your blog in dollars. I tried this for my other blog Tech Spikes and this is what I found.
As you can see, Cubestat has estimated the value of Tech Spikes at $33,559.86!! Anyone interested in buying it? 
Check out Cubestat and estimate the value of your blog.
