The sidebar was becoming very long on this site. (Did anyone ever actually scroll down far enough to see the blogroll? ;-) To try to simplify things a bit I have moved a lot of the content from the sidebar to a series of tabs across the top of the screen. I hope it works for everyone.
I still have a longer term goal of doing a more significant site update, but that will have to wait until I have a bit more time to work on it.
