Whilst I have really enjoyed building this little website, and slowly beginning to write a little more, one thing that has troubled me the whole time is how to facilitate conversation on the topics I bring up in a way that I can believe that the person making a comment is actually who they say they are. Or, at least, they are the same person I interact with on other platforms as that identity.

"Oh that's easy!", I hear you say, "Just use a tool that allows someone to login using their identity elsewhere - lots of ways to do that, such as OpenID."
