If you run a blog or other web site, odds are you already know how important social bookmarking sites like Digg, Reddit, and StumbleUpon can be for generating traffic. But while you may be used to seeing large traffic spikes from these sources occasionally, over time social bokmarking sites can give you yet another gauge of your blog's popularity. Have your stories been Dugg or stumbled more times than your competitors? SocialScan makes it easy to find out.

Just enter any URL into SocialScan and the service will look up the site on 12 different social bookmarking/news sites. Some measures are more thorough than others. For example, you'll only find out how many times that exact URL (ie: your homepage) has been submitted to sites like StumbleUpon or Reddit, while the Digg results will show any time a web page starting with your URL has been submitted.
