One of Reddit’s biggest communities is suggesting users move to Discord
(www.theverge.com)
This is a most excellent place for technology news and articles.
They probably already know how to use Discord, so they think that it's easier to migrate their community to a service that they already understand vs. researching an alternative, learning how it works, and then trying to migrate their community.
Also, a lot of their members are probably on Discord already, so you don't have to try to convince them to sign up for a new service on top of everything else I mentioned earlier.
