The only trust that I am expressing with that signature is that I have seen and verified, to the best of my ability, some form of reliable identification for that person (ideally a passport I can verify, or a social environment in which it would be very difficult to impersonate someone you are not) in combination with a proof that the key I signed belongs to the person whose identification I checked. Just because someone attended a key-signing party doesn't mean that I would, say, trust them to install software on my system. -- Russ Allbery (rra@...nford.edu) <http://www.eyrie.org/~eagle/>
