It can definitely be annoying because sometimes the latency is long. For example, I may be in another window and not see the "hey" right away. When I reply, I may wait half an hour for the person to explain why they messaged me, but I won't know how long I'll wait when sending my reply. I don't think it's a problem if someone says hi, then immediately types their question. But if they wait for an ack it can be kinda silly.
