I find it very hard to judge whether I'm fulfilling that part of the guidelines. I only have a few submissions, and I think I'm good there, but I'm more conflicted when it comes to upvoting or engaging in other people's submissions. For example, earlier today I saw a thread on German laws on date rape drugs. I upvoted the thread. Do I think it's important for people to talk about date rape drugs? Certainly. I'm not sure if it falls under satisfying my "intellectual curiosity", though. Is HN "the right place" for this conversation? I'm not sure, though I think the reality on the ground would say "yes". Most likely, all of this is an organic adaptation that HN has experienced.
