Validation is for losers.
Ahem. While "pass/fail" on a validator, particularly the W3C's, should not count for everything, it can show poor coding practices and things which may work different ways on different browsers. For example, the webplore.com page has JavaScript code between </head> and <body>! There should be no content between those two tags. Other things, such as lack of alt= attributes on minor decorative graphics, or the use of self-closing tags under HTML, are forgivable. A validator is a
tool to help decide what's wrong (if anything) with a page. It's about as "macho" to develop pages without validation as it is to see how drunk you can drive.
