One of the designers on my project has been buying $5 web 2.0 terms from shady characters in back alleys. I know this is a real model/concept, and therefore; not something you can ask a generic question about. So all I'm after is some resources. Rules, ideas, concepts, thoughts, models, tests - whatever.

If you got links, post'em. If you got opinions, post'em also. If you've been burned trying this, by all means fill me in.

For those not familiar with the term, it's using HTML and CSS to support multiple resolutions. Things grow, things shrink, things look like crap - but not as crappy if they were statically sized and positioned.
