I found a WordPress theme that I mostly like called Hal 5.0.  I think the top image is a little over the top, but the overall theme is ok.  I edited the font size up from the default – the font designer must have amazing eyesight.  I also added in tag listings into the blog posts.  Overall, I’m much happier with this look than with the previous one.  I still think that, someday, I’ll make my own theme so I can be completely happy with it instead of finding one that’s good enough on the WordPress site.
