Back in 2006 I was working on a venture I called SocialNet (MySocialMap), based largely on research by dinah boyd and the Vister application she and Jeffery Heer put together. The idea was to build a icon based visual map of relationships across multiple social networks and layer this with a Taste Fabric styled algorithm. Users would be able to visualize their relationships across social networks (something still not done well) as well as discover their networks propensity to like anything from brands to movies. After a couple of successful beta applications the initiative got bogged down in a bunch of issues from vendor management to time constraints (not to mention SocialStream). I had to shelve it late last year after a ton of work and a couple grand in expenses with only a barebones prototype to show for it.
