Asian here. Yeah, it feels a little rude to start asking questions without first going through the equivalent of a SYN+ACK handshake. I usually compromise by sending two messages in quick succession. I write the actual question first, Ctrl+X it, send a "hi" first, Ctrl+V the question back into the textarea, and send it immediately afterward so that I don't waste the recipient's time.
