Me too is not that interested in most communities here. All you have to change is the default setting in your profile to "subscribed" instead of "local". That's the same mechanism as reddit had.
But yes, the amount of discussion here is limited. But not in a bad way. More like, concentrated rather than spread out. If you want to give it a try, go here:
Just look up the most active community for your specific interest and hope for the best. Worked for my few interests.
I give you that. However, I feel like the amount of times this happens here feels far more natural compared to reddit before the APIcalypse. Like, depending on the community, visiting a bar can be either peaceful, fun and full of interesting conversations or end I a bar fight at worst.
Reddit felt more like a completely overcrowded mass bar full of assholes in comparison. You had to actively look for the nice circles usually and hope they don't implode quickly.
