I'm by no means a grammar nazi, but really, how hard is it to get less / fewer right? I just got NCAA 2010 in the mail, and on the gameplan screen (the one where you choose between being Aggressive / Normal / Conservative), the game mentions that adopting a conservative defense will give up "less big plays".
Honestly, how does this happen? Was there not a single tester that looked at that and was like, hunh, that's a mistake?
Use "fewer" when you can count the the items in question, like "big plays" or "pounds Weiss has gained in the off-season".
Use "less" when you cannot count the individual items in question, like "girth of any combined 5 average Americans versus Weis".
