There's a lot of variations so even some natives will share your frustrations, though personally I think the option variety is a nice feature. You can have amusing moments when you've queued up an automatic response and get the wrong trigger. "Gorgeous day huh?" "I'm well, you? Err..." Sometimes just ACK-ing works well if you really don't want to think about it... "What's up?" "Sup." "Howdy?" "Howdy." Regional / cultural greeting patterns can be used though to initiate moving from total stranger to closer stranger more quickly when you reply in certain ways... "Wazzup?" "Wazzzzuuuuup."
