Indeed.  Then you only need to trust the two people on the path to
anyone you're trying to talk to.  Also, you have to account for the
fact that people do (and will continue to) keep multiple online
identities -- I'm not sure how that complicates things, if at all.

Well, if you can do any web-o'-trust routing then you're presumably
using something PGPish -- you have keying.  Therefore you have no
excuse not to encrypt.
