All well and good, but... (Score 1)

The W3C Validator is useful in validating your code so that it is "valid", according to the standard. Problem is, I've yet to see any browser that properly implements every aspect of the W3C standard, so isn't code validity a bit pointless if it's not going to work properly in the market leading browsers? That's what annoys me about web development - nothing you ever learn works for more than two minutes, if it even works at all.
