As an open source project, we should have an open source friendly chat platform as well, like IRC, almost any open source project is there, just not us.
Discord has many issues here are some examples: https://stallman.org/discord.html
I also think it reduces activity in the forums, which is very bad and your force people through peer pressure to get another program and register there in order to take part in the discussion there, since Discord is not a free open platform that is visible to anyone like this forum. Why not have an open platform for chat as well? It takes almost no efford to register an IRC channel, does not require installing external programs and does not require anyone to register anywhere in order to take part in the discussion.
