> I couldn't tell from the startssl.com certificate just what its $60 product is, but as the description includes the phrase "organization validation," I presume that product has both the CN and O field filled in, whereas the free product has only CN (like lwn.net)
Actually, both individual validation ($60) and organizational validation ($60+$60) will include O, L, ST, C and emailAddress, but for individual validation, O will contain the name of the individual validated, not the organization for which the individual works. I.e. for lwn.net the difference is whether it would contain "O=Jonathan Corbet" or "O=Eklektix, Inc.".
A free certificate from StartSSL will only contain CN, C and emailAddress.
