Oh God, I'm so embarrassed!
Can we go back to talking about less versus fewer? That one I can at least do.
Or using "me" instead of "I." As in, "it's me!" Nails on the ol' blackboard there...
Less vs. fewer is one that a lot of people get wrong. Of course a lot of people get "a lot" wrong as well. "It's me" can be correct sometimes. For example:
Which word out of "me" and "I" would be correct to end this sentence: "x happened to John and ..."?
It's me!
And I think most people accept using me with it is, because of common usage. If you say "it is I" you sound a little bit stuck up. There's an interesting discourse on the matter here: AUE: FAQ excerpt: "It's me" vs "It is I"
There have also been a couple of interesting ones about ending sentences with a preposition. Word has it one of Churchill's proof readers read the script of a speech Churchill had written and wrote on it "you shouldn't end a sentence with a preposition". Churchill responded with something like "this is the kind of insolence up with which I will not put".
