> At my job in 2011, every single member of my team was on using a different client...
This persists today - every single person I communicate with uses a completely different app, including SMS and email. I only know one person who uses WhatsApp, but serval have dumbphones.
Coordinating with more than one person involves at least 2 chat programs and a website. "Group chats" are impossible because in 2017 we still can't group chat between 1 person on Skype, 1 SMS, and a Facebook.
At my job in our division we use Slack, anyone outside uses company email to get a hold of us. I'm of course speaking of work. Out in the real world with friends and family, everyone has Facebook, so it's as easy as that. I can also just text / call them. I think Discord is probably the best way to create "Group chats" everyone can just join without even having an account, and you can use voice chat or text. I've never had issues making a new Discord and linking someone to one, they always just join and it rarely dies out.
