I stopped using WhatsApp years ago. Yeah, it was slightly inconvenient because of course friends and family were using it (which was why I started using it in the first place) but I told everyone I would move to Telegram so they could contact me on there or they could keep in touch through text/email/calls. Plenty of options.
I installed Signal on my phone years ago but no one I knew used it. So I couldn't use it even though I did have it installed.
Now I'm in a similar situation with Telegram as I was with WhatsApp, except more and more of my contacts are joining Signal thanks to everything that's going down at the moment. There are, unfortunately, still a few people that seem to be out of the loop and still continue to use Telegram so it's still installed on my phone but I mainly use Signal now.
So I'm glad more and more people are discovering Signal and are now switching! Now I get to actually use it.
What's the best way to self host it?
