For me, Google video search, Google books (Internet Archive is good, but doesn’t always have the same stuff), Adobe InDesign (but in the process of learning LaTeX), and Typewise. As for the Google stuff, I liked Whoogle a lot, but almost all their instances seem to have been blocked or shut down. Also, apologies if this is repeating an earlier post.
In some countries, government employees themselves use WhatsApp to communicate on their work phones. You have a query? Schedule an in-person visit in 6 weeks, or fire up WhatsApp, your choice. Fortunately some also use email, but WhatsApp still tends to be quicker.
It gets slightly worse when you’re looking for a job, and the only way to get hired, is to talk to someone through WhatsApp. Don’t want to? No job for you; next!
Yeah, WhatsApp is amlove hate relationship for me.
It’s seriously the best app out there, it just works, works nice and intuitive, has a web version (holy crap can’t go without) and almost everyone is on there.
I’d love a Foss federated solution, but good luck with that if no one uses it
