I just started a community for developers on a discord server and it seems to be scratching the itch for a lot of people. We can only be found by word of mouth, which has it's pros and cons - fewer members but high quality conversation it seems.

So I think there are communities still out there for people, but like the article said, they can be hard to find/know about. But you're welcome to join mine if you're interested in software dev team chat: https://discord.gg/tpkmwM6c3g
