I hesitate to beat the prescriptivist/descriptivist dead horse. But I have a particular observation about the "less"/"fewer" issue that I think deserves to be pointed out to more people.
You're probably all aware that there is a history of some people saying that the word "less" should not be used with count nouns or discrete quantities, but only for mass nouns or continuous quantities. "Less cows" or "less problems" is considered incorrect by many people (they say it should be "fewer cows" and "fewer problems") but of course "less milk" or "less information" is fine.
You're all familiar with descriptivists vs prescriptivists in general, and with the "less"/"fewer" issue in particular. Many of you probably know that in fact, English has a long history of using "less" with count nouns, and the insistence upon "fewer" seems to stem from one writer's personal preferences around 1770.

I lean in a descriptivist direction, and most of you seem to as well. Nevertheless, I'm aware that many people object to "less cows" and "less problems", and in fact, especially in formal or professional contexts, I personally would probably give in to the pressure, and say and write "fewer cows" and "fewer problems".
I will admit that even to me, "less cows" and "less problems" seem slightly "off", and even though these things are often ultimately arbitrary and come down to aesthetic preferences, I have no doubt that people are being sincere when they object aesthetically to "less cows". Some people have a very strong distaste for that construction and find it grating, like nails on a chalkboard, and I believe that their aesthetic reaction is real.
Here, though, is the point that I'd like to make, and the observation that I'd like to make more widely known. We use the word "more" for both count nouns and mass nouns, and nobody objects. We happily say "more cows" and "more problems" as well as "more milk" and "more information".
From conversations with the folks who are opposed to "less cows", I gather that some of them think that "less cows" is somehow indicative of sloppy or careless thinking -- as though people who say "less cows" are unaware of, or insensitive to, the distinction between count nouns and mass nouns, or number and quantity, or discrete and continuous.
Such an objection is silly. I happily use the same symbol '<' when comparing integers like 3 < 5 and when comparing real numbers like 3.4 < 3.8. I use the same symbol even though I'm aware that the integers and the real numbers have different properties. We all happily say both "more cows" and "more milk" even though we understand why "three milk" or "five information" doesn't make sense.
I kind of want to say to those who object to "less cows", is it a defect in the language that we say both "more cows" and "more milk"? Is it sloppy to say both "more cows" and "more milk"? Does it lead to confusion? Would the language be improved if we had two different words for "more"? (We set aside the practical question of how to get people to "convert".)
If people want to object aesthetically to "less cows", I can't really stop them, and it's hard to argue about taste. But the double duty of the word "more" shows that the distinction between "less" and "fewer" is not a distinction that is somehow forced upon us by logic or mathematics.
