Nobody gave a shit about my status to contact me elswhwere. People just open the existing conversation and never see it anyway. And most don't care, or want to switch.

Whatsapp is THE messaging standard in my country. Hell, even our politicans use it for communication. "Apping" is even used by news outlets to describe communication by Whatsapp.

We used to have SMS and MSN. Now it's either Whatsapp or Messenger. Depending only on the fact if you have the others phone number or not.
