Unrelated to the blogpost in question but I don't understand why the author is not using its own certificate if he is using his own domain. Using an browser set to autodirect to https by default, all I get is some huge warning because the host use a certificate for svbtle, the service used to host this blog. I know some people think that because some blogpost is public it can be served without ssl, but I think it is still nice to leave the choice of the reader to disclose or not to his provider and everyone in between what he is reading or not without seeing horrible warnings.
