Dont confuse standards and validation. Web standards are of course critical for the workings of the web. Validation is highly overrated though. The reason people get hung up about validation is that it can be performed mechanically and gives an unambigous result. However it only check against a small (and pretty unimportant) part of the specs. For example a validator cannot check if you use semantic markup (which is pretty important), but will complain about superficial and harmless errors like leaving out the type attribute on a script tag.
