There's an adjustment period to understand each boards specific signal:noise. You can't just walk in and find Aristotle and Kant figuring shit out.
Each board has its ridiculous bullshit, groupthink, absurd extremists, edgelords, etc. once you know how to parse that you can quickly navigate to quality posts.
Each board of course has different signal:noise though, somewhere like /lit/ is probably 1:20 whereas /pol/ is probably 1:500-1/1000. But the quality posts are totally different from what you'll find anywhere else. Different users and audience.
