In response to feedback from a couple of people, I have opened up the Comments feature to all users. This should make it easier to leave a comment without having a Google account.
It also means you can comment anonymously, although it will be easier to carry on a conversation with you if you leave your name. Unless I don't know you, and you've happened on this blog by mistake, and you just want to say something ugly. Then I'll delete it. Quickly. Because I don't have a job, and I spend a lot of time here right now. (Ha! Take that, imaginary, anonymously mean commenter!)
In other words ... comment, people! Yes, I would do this even if nobody were reading it, but hearing that someone is reading it once in a while makes it a whole lot more fun.
If you try to comment and it's still not working for you, please let me know that, too. Not that I will probably do anything about it -- when I fell upon the radio button that allows anonymous comments, I pretty much hit the ceiling of my Blogger knowledge. But it would still be nice to hear from you. :)
