Subject Re: Key Signing Party Anyone?
Date Thu, 24 Jul 2014 21:37:04 GMT

I am not going to dispute the social benefits of a party, but can't we 
achieve the same level of trust by placing the public key in our Apache 
area, or by committing it to svn? Then for sure we know the key belongs 
to that committer, right?
