I've been an early adopter and watching this app grow over the years has been amazing! Discord is a fantastic piece of software!
I've been able to replace most of my social media use with it. It's like a hybrid of everything you would want: forums, streaming, messaging, and voice chats (similar to slack huddles, or old school VoiP stuff like teamspeak or ventrillo, but much better). The engineering department is fantastic, and they have been ramping their development in recent years, and refactoring services for performance (read the somewhat recent go -> rust refactors over the past few years). I highly recommend!
