Google has released a Social Graph API that allows to see how things are related on the web using only pubiclly available data. One of its many features is maping how your websites are related. If I input my websites into the demo:
http://del.icio.us/baileycross
http://www.grilldemon.com
http://baileycross.com
http://pdxtransit.com
http://kitchenandlaundry.com
linkedin.com/pub/2/681/106
twitter.com/baileycross
it assigns a score indicating how many of your claimed sites can be reached from each url. Maybe this has some applications for SEO. Not really sure at this point.
