Herkko Hietanen, a Berkman Fellow, posted this to a mailing list. I’m reposting it with his permission, FYA (for your amusement):
I have been using Facebook for a while with an account name which is the Finnish equivalent to “Ano Nymous”. My aim has been to see how the service adapts to information that other people tell about me. I have tried not to tell anything to Facebook about myself. Or, well I did tell it that I was born on the Finnish independence day in 1917. Of course the service does know my 20 friends.
Today the system suggested that I should join two groups. One is “Cambridge”, which I guess the system determined from my IP address. The second one was “conspiracy theories” -group.
Is the irony of the service starting to get off the scale or what?
