Same. I used reddit mostly for smaller communities and the hot algorithm doesn’t seem to pick them up here. They’re pretty inactive but they do have daily posts. If I don’t go directly to that community though, I won’t see them. I’m sure these things will be refined over-time.
It’s funny whenever this is brought up on a reddit admin post. They always come with some stat saying a tiny % of users use old.reddit.com like that means people barely use it and therefore useless. But I see a lot of active posters talk about it which means those are probably the users you want to keep around lol.
