So call me slow, but yesterday I decided to catch up and give CSS another chance. What did I discover? The little kid grew up, browser support is now widespread and generally excellent, and I can finally cast aside my table and transparent pixel baggage. At the end of the day, it boils down to throwing away unnecessary code, and that's one of the best things that can happen to a hacker.
What I'm wondering now, though, is how to avoid delaying this kind of enlightenment in future. At some hard-to-define point, using a particular technology flips from being a liability to a superability. I want to define that point for myself.
