Are we doomed?
Decentralised social networks from a postprivacy point of view?

Michael Seemann:
privacy,
decentralisation,

I must say I had to bang my head on the desk several times when I saw this talk. But there have been also some interesting statements about network effect, Metcalfe's law, social gravity, economies of scale, transaction costs, query, etc.

Unfortunately this talk was in German and the automatic subtitle is terrible :-(
