Wow.
Just read this post by Mullenweg on the Gravatar blog. I had no idea this was in the pipes, but man, am I glad!
BTW, all the premium Gravatar features are now free, and it’s being merged with Wordpress.com’s avatar service. So be on the lookout for many more commenter icons on the way!
It’s funny… all it takes is a little thing like this to brighten my whole day. 
Apparently y’all have been getting an error message every time you try to leave a comment.
Shame on you! You should have e-mailed me! (Okay, those of you who had my e-mail address.) My darling wife just let me know, and it’s probably been at least a week now…
Look, I understand the occasional anonymous comment or remark… it’s just that lately, that’s all I’m getting. It makes it hard to respond to someone who won’t even give you a name to work with.
If you want to be silly, that’s just fine: the "F. Glomgold" comment on my Life and Times of Scrooge McDuck entry was written by David Gerstein, a friend and co-worker. That’s humorous, and I have no problem with such things. Just don’t leave it "anonymous"… please. Doing that is so boring, and it makes it seem like you’re trying to hide or something.
