Thawte Will End "Web of Trust" On November 16
An anonymous reader writes "Thawte is ending their Web of Trust, including their free Personal Email Certificates, in less than 2 weeks' time. This hasn't been picked up by the media yet. Seems to me a lot of people, including myself, are hurt by this." Thawte is offering a 1-year free VeriSign cert to those holding valid Personal Email Certificates; after that you pay.
www.cacert.org has an alternative web of trust that issues both client and server certs.
You're post is an example of how people don't understand PGP, not that there are any technical limitations. Looking in my enigmail key manager, I have a whole list of keys (automatically downloaded) that are not trusted. The few that I have verified are trusted. If someone signs "almost everyone's" keys and isn't trustworthy you don't trust them. If they are trustworthy, then you just made use of the web of trust.
You don't have to trust everyone in a Web of Trust that originated from you. It just tells you who trusts that person. What you do with that information is up to you. Also, there are several levels of trust. You don't have to sign anyones key, just the ones you met.
GPG is right to download the public key from a server, because that tells you nothing about how much you trust that person. If it would set that person automatically to fully trusted, that'd be a different story.

The only way to see whether the form is secure or not is then to view source and check whether the form action has https or not. I don't really believe that grandma is going to bother...
