Honestly not many yet. The Steam deck one seems to be great so far, same with pcgaming, even if they are small. My niche communities are where it’s getting hard honestly. Like I’m an upholsterer and I don’t think there is a community for that. Maybe I’ll create one, idk yet.
That's where I'm at. I mostly only commented on smaller subs that either don't have equivalents over here, or they don't have much activity. Never really posted at all.
All those communities need someone to kickstart them and get the ball rolling. Even if its just you using that community as a bookmark folder at first, it will be something. And then maybe someone else finds it, and they start posting, too. Suddenly you and this other person are having conversations. Now you have entry points for more people
