And there's 'nothing wrong' with just writing code with variables named 'a1, a2, a3'. But when some poor sod has to dig through your mess to figure out what you had in mind it turns out that having an easier to discern logical structure to your code (or html) makes it better. I've dug through a lot of html. And there's a ton of ugly code smell out there. Layers and layers of "I don't really know what I'm doing but I guess it looks okay and I'll make it make sense later". I'm sure it pays the bills for someone. But it makes me sad.
