Well it has started has voice chat for gamers. Their latency and sound quality is top notch. You can have voice call with 5000 people. You can finetune sound of each individual. They have mass moderation tools... it surprises me with something in a good ways.
I've personally been in voice calls on discord with thousands of people. Obviously it's impossible to pick out anything discernable with that many people but discord handles it well.
It feels like theyve nailed the technical part.
