Shorter version: pedantry sucks. There was little to no insight in the original, it's just a list of stuff that can reasonably be argued to be "good". Those rules won't a great product make, but breaking them doesn't seem like a great idea for most people either.

My own feelings are closer to this poster's than the original list of admonishments, but these aren't issues that anyone should really be getting upset over. Basically: don't refute shopping lists. It just wastes everyone's time.
