Ever hear of the game Six Degrees of Kevin Bacon? The goal is to connect Bacon and any actor/actress through the movies or TV that both have worked in. An actor/actress has a Bacon Number of 1 if they were in the same film. Finding anyone with a Bacon Number higher than 4 is tough. Try it and see for yourself.

Anyway, my thought is that anything interesting in the area of internet/online technology today is very directly related to identity. I think technology applications have an Identity Number, much like actors/actresses have a Bacon Number. I also think finding an application of technology with an Identity Number greater than 2 is hard. What do you think?
