I’ve just updated the Comments section of the blog, so you can now leave comments by logging in with your Facebook or Twitter account, amongst others. The ability to post as a guest is still present, if you’re that way inclined. You can now also do threaded comments and a whole host of other funky things that you don’t need to worry about because I’ve sorted it all out for you. All of this marvelous functionality is provided by IntenseDebate, if ever you need something similar.
