Hopefully, this post will be OBE in a short while, but I just changed the site over to a very plain theme.  The immediate advantages are not clear, but in the end it’s all kinds of better.  The new theme uses HTML5 to mark-up the site in a more semantic fashion.  Instead of everything on the site being enclosed in a <div> block, posts are within <article> blocks, sidebars and navigation elements are labeled, etc.

Of course, there aren’t a lot of themes that have this and a design that I like, so I’m starting with a basic H5 template, and will work from there.
