Saying hi can actually cause disharmony by confusing newer team members:

For example:

> How am I supposed to respond to a bare 'hi' after I asked a question?

I've never had anyone ask me such a strange question. I think most humans know that when someone says "hi" you say "hi" back, I don't see how that could be confusing to new team members.
