As a gamer, Discord is my most difficult to replace anti privacy platform. It is “the social media for gamers™” after all.
I’ve tried Matrix many times, and every server I’ve joined has felt dead. I couldn’t find many gaming centric communities there either, and absolutely none that had any activity.
Do you still use Discord or have you successfully replaced it?
You’re not asking for a platform. You’re asking for alternative communities.
Communities are the hardest thing to move. Fact is, people use discord because the people they talk with are on discord. Same as any other social platform.
