Sometimes one needs to adapt to the outer world :) I use Whatsapp even though I hate instant messaging and phone calls (I like communicating at my own pace when not face-to-face, and I dislike any sorts of smalltalk on the phone or messaging), because communication is a two-way street, and sometimes conforming is easier. I disable last-online and blue ticks in Whatsapp so it's more e-mail like, definitely improves the experience.
