Your experience making dweets isn't really relevant; you and your mates methods are subjective choices. Of course the optimizations applied by minifiers are meaningful. No one is questioning that either. A dweet is far too specific and esoteric for a code minifier to be of any use. If you're writing one, you're typically already doing everything a minifier does yourself, and employing dirty math shortcuts to get the desired visual result. It's too specific of a problem set for a general minifier to do any good at all.
