I created these forums as a place for more long-form discussion, and for topics that don't really suit discussion on Twitter or Discord.
One of the advantages of a public facing forum is that unlike with Discord or Telegram, anything discussed here can be indexed by search engines. This helps bring new traffic to our communities, and can only be a good thing.
Of course, if there really is a need for private discussions, then there are plenty of ways to do that.
Over time we will create a useful topic hierarchy for ease of reference.
