Gravatars
Not entirely happy with the layout yet, so that may change in the days/weeks to come, but I’ve added support for Gravatars, a.k.a Globally Recognized Avatars.
The idea is that you can associate the email-address that you use to comment here with an image. Once it’s been approved (rated) it’ll show up on any (old and new) comments of yours.
This does not expose your email address to anyone reading along, the image is queried using an MD5 hash (checksum) of your address which is (in practical terms) impossible to reverse.
