I've made a few subtle changes to the site over the past couple of days. For starters, I finally upgraded to the latest version of wordpress. I got rid of the email subscription link and moved the search up in the header. I'm hoping to get support for gravatars into my theme shortly.
Another change I've made is getting a few ads into the layout. I'm going to make sure that the ads are done as tastefully as possible and don't interfere with the content. I'll keep the number and size of the ads down so they aren't overwhelming and obnoxious.
