You may notice that I enlarged the avatars (pictures) in the Recent Comments in the sidebar. The gravatar.com site is finally working correctly, so pictures are now showing up for your ID. The idea of global avatars is really neat, and I’m glad that feature is available in WordPress.
Do you want your own? It’s really simple. Just go to gravatar.com, create an account, and upload a picture to go with your e-mail address. Then when you write a comment using that e-mail address on a WordPress blog (or possibly others, too), the image shows up next to your name, if they have avatars enabled.
One thing I’ve noticed is that I had to use all lowercase when putting my e-mail address in the comment form. Perhaps that will get fixed, but try doing that if you’re having any issues with it not showing up.

this isn’t working for me 😦

it works here, why won’t it work on other blogs??

It’s obvious why it works here and not at all other blogs — this blog is superior! 🙂
Seriously, though, sometimes it takes a while for them to work on all WordPress blogs (although I thought they had that fixed). And, of course, the blog owner must have enabled gravatars.
