Quite often I’ve seen blogs that for their commenting system they have OpenID as an option. I always skip that because I don’t have one. Well, actually I do. I did not realize this but anyone with a number of existing accounts have OpenID built in. Technorati is one of them, so I started using it as my login mechanism to a semi-secret beta (can’t be that secret, the founder Twitters about it). Just for fun, I think I’ll start using that for any blog comments that support it.
