Somewhat related to the rant below about differentation on the web (or lack thereof), Victor makes an excellent point about Jakob Nielsen's comformist philosophy (it's too long for me to quote here, just go read it). While the majority of sites could benefit greatly from some of Nielsen's (perhaps, a bit pedantic) teachings, if everyone listened to him, the web would be a much-less-interesting, much-slower-evolving, not to mention much-uglier, place.
