Nope. I hadn't clicked on them. I assumed that the template writer knew what they were doing
As to whether or not its important to follow them, I would say yes. In a lot of causes that will cause some browsers *cough* IE *cough* to not render the page correctly, but at the end of the day, standards are all you have.
So, interesting story. My company recently got bought by a much much much bigger company whose intranet is one of the 7 wonders of the world. A fair number of pages on that site - mostly web applications - won't work in IE. Quite a change from the company I was with that got bought who would break anything end everything else to support IE.
