Yeah, it's all about communities, not platforms. What happens is that people find a community they like, then the platform underneath it dies (IRC, MySpace, Digg, etc) and they can't find the same community on a new platform. I've made a lot of friends on Discord, and ionce a year or so when it looks like Discord's about to finally give up we talk about our plans to migrate the community to a different platform. But since the community is the important part, we don't really care about the ills of the platform until it starts to actively hurt the community
