I know Whatsapp apparently has a ton of users but I honestly know nobody that has ever used it. A lot of Discord, Telegram, Facebook Messenger, a little Hangouts, and back in the day MSM, Yahoo Messenger, and AIM. I guess I missed that step in the ladder or something. Same with SMS - from the time I made the leap to Smartphones there were already enough general XMPP clients / Hangouts was good enough to never think about using a third party, especially proprietary, service like that. My understanding is Whatsapp took off outside the US entirely because it seamlessly used SMS when data was unavailable and that was certainly a killer feature in many parts of the world.
