I don't comment small subroutines that are "obvious". Like a routine called max. However, a lot of subroutines assume things - they are called preconditions. Personally, I think it's vital to document those. I also tend to document arguments if the sub has many optional arguments (in which I prefer to use named parameters - if you pick good names, just listing which parameters can be used is often enough).

It's not a black & white thing. I think that both those that document all subs and that document none are wrong. Good programmers know which subs to document and which subs can be left undocumented. ;-)
