A little help with Internet Explorer Compatibility Mode

We all know that Internet Explorer 7 and 8 don't always play very well with all websites, so Microsoft has introduced Compatibility Mode for Internet Explorer. While building a new website just now, I stumbled upon a very good article about what Internet Explorer Compatibility Mode is all about. The article titled Understanding Compatibility Modes in Internet Explorer 8 explains it very well. I used the meta tag with "IE=edge" that asks the browser to "Always use the latest standards rendering mode". You might also want to refer back to one of my old posts to find out how to cheat Internet Explorer to do different stuff than other browsers: Internet Explorer CSS "cheats".
