I was thinking the same thing. Having a chain of signed PGP keys that allow you to infer the trustworthiness of someone hasn't seemed to catch on. Are there any good articles on how this idea developed, and succeeded and or failed (I'm sure it was/is in very heavy use somewhere or among some group)? Heck I once went to a signing party... http://en.wikipedia.org/wiki/Key_signing_party http://en.wikipedia.org/wiki/Key_signing_party
