There's a whole thread dedicated to the Discord server of Sythe. Googling "sythe discord server" would give you this as first result: Official Sythe Discord
It's just an addition to Skype so there's voice chat too as far as I know. Besides that there was an suggestion made to require Discord for trades in the future, instead of Skype, but that was rejected if I recall correctly.I was just asking why more people don't use it. I wasn't wondering about it.
