In their own words

"Digfoot was founded by me (Bo Kjaer) when I, after a move from the US to Europe in 2006, became frustrated with the lack of integration and visibility across worldwide social networks. I have over the years lived in a number of countries and of course got to know a lot of friends at different locations.
I soon realized that it was something of a challenge to find old lost friends again once you ventured outside the US since local networks in for example Germany or Spain have very little crossover users with the major US centric networks such as LinkedIn, Friendster, Facebook etc. What I thought could be neat would be to have some kind of central place where all the social networks could be found and then use that as a starting point for branching out into other networks looking for those long lost friends and business connections.

Well, that was the initial idea that I started sketching out on my notepad and that later morphed into what you are looking at today - version 1.0 of Digfoot.com - which was launched in August 2007 and still is under hefty development so expect frequent improvements and updates."

	Why it might be a killer

DigFoot.com lets you bookmark sites so you can come back to them later. If you find a social network interesting add it to your notepad so you can see it again later. The rating system also is helpful so you can see what users of the site think about it. The social network list on DigFoot.com will continue to grow because it allows you to submit your social network if it is not already on the list.

	Some questions

DigFoot.com does let you browse through many networks but some times the search is not filtered enough. For example, is you want a photography network, the search shows up with all networks that feature photos in general. Maybe there could be a more detailed filtering process. DigFoot.com has an extensive list of social networks, finding a long lost friend among them may be impossible.
