Discord was originally for gamers, yet has picked up a variety of topics and servers to choose from (not just games). I've been there for almost 2 months now, joined to research and participate in the Ohm Wallet Chat Server.
It is similar to an IRC Chat Service.
As well, it is accessible on a desktop through a browser with no need to download the app (if one has access to a PC or laptop).
To be honest though, between chasing notifications on steemit and discord and facebook and SVV (ARG) and emails and..... I'm beginning to think I may never be able to go outside to play ever again!
