My site has been basically the same for over three years without any major changes. Recently I cleaned up all the code to make it HTML 4.01 Transitional compliant, which required rewrites of a lot of sloppy HTML. I changed the way I present video, added mobile detection, hidden <div> overlays for some links, and made better use of valid CSS. Now my testing shows it is almost perfectly cross-browser compatible for IE 7-9, Firefox, Chrome and Safari, and passes the W3C compliance tests. I'm really happy with the results.

Yesterday I added a photo background to my banner and I think the color adds a lot to the site. My menu structure was also getting a bit large so I consolidated all the data elements into one submenu which significantly reduced the main menu choices. I like it.
