I've switched the comments setting for my blog to "only registered users may post comments." That means that if you're already a Blogger user, you just log in with your Blogger account and comment away. If you're not a Blogger user, but you've got a Google account, like Gmail, you can use that. If you don't have either one, you can register for an account. I realize this might be a pain in the ass for those few people who just like to send me a quick response, but I've gotten some weird comments lately, and I want to prevent any other comment spam from appearing on the blog. If you've got a problem with this change, post something in the comments.
Or you could e-mail me instead.
