Special thanks to Ike at Occam’s Razr for pointing me towards a site that highlights who you are and what web services you have a membership to. The services (Flickr, Last.fm, etc) listed are vast and almost exhaustive.

Onxiam is simple and does have a community feel to it in that you see what other sites you have in common with other folks.

If you’ve got the time, fill out your member profiles and get connected.
