I don’t know why people continue to have such ugly comment pages when it is SO simple to set WordPress to add a unique avatar to everyone’s comment. For users without a custom avatar of their own, you can either display a generic logo or a generated one based on their e-mail address.

All you have to do is go into the dashboard and click “discussion” under settings. Then scroll down to the bottom of the page and select a different avatar image. I use Monster ID because I think it is kind of cute, but if you have a more formal blog you’ll probably want to use Identicon.
