Telegram is nice for instant messaging: it's simple, cross-platform, does well with resources, and run by a non-profit org. Yes, russians might be spying on it. FB/G are spied by others. Meh. (There's Signal as well, but I like my SMS separated.)
Google Docs are terrible anyway: slow, lacking lots of features. Libreoffice or (god forbid!), installed M$ Office - and share the docs on, for example, Dropbox.
However, it's already very hard to tell people what the web used to be. Just read the entry "I’m 22 years old and what is this."[2] - web devs being in the business for <10 years may not even remember how it was before G or FB. I'd welcome any ideas how to address this.
