Everyone I know uses Discord, even my 59 year old mother. It makes sharing stuff with her, including streams, super easy. I can't imagine trying to convince her or anyone else to swap to Matrix. Plus I'm part of multiple art communities on Discord.
@Calcifer Reading can be free with a library card. I use Libby on my phone to check out books. But if you'd rather not have to wait for more popular releases, Amazon does have Kindle Unlimited. I think it's $12 per month, you can check out something like 10 books at a time.
Edit: I totally forgot about Scribd! Way better than Kindle Unlimited cause it has audibooks and Magazines too, for only $12 a month.
@Errant I've been playing Diablo 4. Got a lvl 60 softcore Rogue, been playing since the 1st. Taking my time to hit 100 cause I don't want to burn myself out before the first season. May make a Sorc or Barb then.
