While I'm trying to fix technical problems with another post: FYI, I switched the commenting on this blog so that the comment box shows up right under the post rather than the pop-up window. I'm not sure why this should make a difference, but it seems more convenient.
I've noticed that blogger designs in general don't seem to encourage discussion, although I'm not sure exactly what the problem with the format is. Obviously content is the main thing, but I visit a variety of blogs and the blogger ones always seem a little low on comments. Anyway, I don't know enough to mess with coding, but if you have any tips or tricks, let me know.
