I got some time to spend on this site this evening.
The most obvious change is the visible one, I have changed the theme to the Mogle theme, I like the three column layout better than the old two column layout. I also prefer the black, white and orange scheme.
The next visible change is the addition of the Subscribe2 plugin. If you register as a user of this site you can receive an e-mail alert when new posts are made. Alternatively you can just stick with the RSS feeds. There are made more prominent by this theme as well.
The last change is the addition of the WordPress.com Stats plugin which will allow me to see how many visitors I get.
