Here 99% of my messaging with real people is covered by VKontakte and Telegram. I can't even fathom using WhatsApp for any kind of serious communication because of how inconvenient and unreliable it is. "Can't download media, please ask them to send again", my ass. What kind of engineering does even lead to this?! And the fact that I have to use my phone while sitting in front of a computer is a non-starter. The web version still uses the phone and occasionally wipes itself completely so you have to set it up again.
