Yes! Just make a discord username, and you can 'explore' for communities. Find one you like - for example, Big Hat Logan, there are quite large communities for Dark Souls and Elden Ring respectively. Then just start dropping hot takes! It's just like this place! I'm kidding. You should probably lurk for a while until you understand the community vibe.

That's going to be a lively place though. You might wanna try searching for smaller communities for more niche things.

That's for discord, anyways. My wife uses Facebook for her things (much to my chagrin).
