I don't think my style ever really changes, but I do adjust the level at which I pitch posts according to the types of responses I get, particularly if I'm trying to explain something to somebody. That's part of being a good teacher. If you talk above somebody, they won't get much from the conversation, and if you talk below them then they will just get bored and not want to continue the conversation.
I definitely adjust the length and thoroughness of my responses in response to the kinds of replies I get, too. If somebody can't be bothered to think and write a decent reply, but instead has a knee-jerk response or a one-liner, why would I continue to waste my time on them?
