How do you prefer to communicate with people online?

Personally I don't give out my phone number unless I really know someone, I prefer to use discord and I'm always happy to give it out to anyone who asks, but there are so many different ways to communicate, do you use a chat app, do you video chat, do you go old fashion and talk on the phone, do you use multiple ways for different people and reasons, most people i talk to are players from a game called Torn so discord is kinda required for the more active player, but its the only thing I use. What do you use and why? Is there a difference?
