Let the SEOmoz page strength tool tell you.

Page strength is NOT Page Rank, it’s SEOmoz’s own invention, but you may find it interesting to get a quick report on your domain. It includes Google Page Rank, Technorati links, DMOZ listing (good luck!), Google position for your domain, age of domain,Alexa and a few more. A diverting few minutes that may be of interest.

The accuracy of these tools is never 100%, but you may learn something new.
