Sites that are organized, so much that any idiot can figure out what to do and where to go. Sites that embrace technology without piling it on. Site that make us laugh, make us think or make us dance. Sites that take risks. Good writing is a HUGE plus.
Some people make hockey look dull, while others make math look thrilling.
We're looking for the latter. And so on. Pages loaded with useless animations, pointless plug-ins, and java for the sake of java. A good site is always under construction, so we don't need signs telling us that. Sites with unnecessary frames, pop-up windows, menus and anything else that would scare your grandmother.
