Did anyone already try ambiently.com. It's a web discovery engine searching for pages related to your current page. Nice tool.
You can leverage it for checking digital footprints.
For example try to use it with your linkedin profile.
I didn't drag the toolbar but it looks similar, only more indepth, to using the related search on google. In google you can use related:linkedin.com to find websites that google thinks are related/similar to the site you listed.
