I just read this story from Jack Humphrey’s Friday Traffic Report:

Even though the tool in still in development phase, it sounded good. It basically allows you to check to see if a site or blog has already been submitted to Digg, StumbleUpon, and other social media sites before you submit your version.

This is a time saver…
