I like getting feedback from the site. Most of the time it's good humoured and sometimes people even take the time to point out a mistake I've made. But sometimes you have to wonder why you bother. For example, I got this charming message the other day:-
"You're wrong about "I'm good" being "MTV English". It *is* correct because "is" is a linking verb, and therefore "good" is a predicate adjective describing the noun "I." See: http://grammar.qdnow.com/2007/04/19/good-versus-well.aspx
"I'm well" is also correct but only in the circumstance of describing health. Maybe you should try to understand linking verbs before giving incorrect advice! or just calling them "sensations."
Note - I said on the page "This is what I call MTV English." Why? Because I'm British. In the same manner I have friends, not girlfriends or boyfriends, and when I hear, "I'm good," it's like nails being dragged down a blackboard - screeeeech - and I'm very tempted to reply, "Yes, I'm sure you are."
So, if you want to avoid the pedants, grammarians and linguists: When someone asks you "How are you?" just reply, "Fine thanks." If you are in a formal situation it is still best to stick with, "I'm very well thank you."
I've posted this here because life is too short and I can't be bothered to get into a flame war. So, consider it my final reply on the matter.
