Learning Web Design from Oz
I found Brian Alvey's contribution to A List Apart Everything I Need to Know About Web Design I Learned Watching Oz to be dead on target. His opening discussion regarding limitations are what drive creativity, is one of the best criteria dividing those that understand the Web and those that do not. This separates the good from the great. The Web has a great amount of limitations, before you get to clients and their boxes they want to work with in. Must we forget the users, didn't think so. The users give us an even smaller pallet of elements to work with.
Personally I find all of this very fun. Much more fun than a TPS report and so much more satisfying.
