SO incentivises some stuff. You ask a question and you get points if other people upvote your question. You answer a question and you get points if someone upvotes your answer.
You can't vote on closed questions or answers to closed questions.
A question can't just be closed. There needs to be a reason to close it. "This question is a duplicate of this other question" is frequently used. Often the questions are similar but different enough to need a new question. You can't ask a broad question to capture all the variation - that'll get closed as too broad. You can't focus in on your exact problem -that'll get closed as too narrow. The gap in the middle is full of dupes. It's pretty demoralising to have people picking over your question and closing it for (seemingly bogus) reasons or asking for pointless clarification.
I understand that SO is about building a knowledgebase but isn't it clear that a lot of people view SO as more of a Q&A + forum? When you close a question, it feels like censorship, which is frustrating because continued discussion and up to date answers are almost always expected.
Anyhow, SO isn't the same site it was 5 years ago. It's actually pretty darn toxic for new userbase and seems to cater to the mods themselves.

That's another frustrating gap in SO: the absolute ignorance of the notion of time and change. Both questions and answers often have a significant timeliness attribute (ex: what are the best online resources for learning <x> as of Jan 2015), and SO has no support for this. To be fair it's a hard problem, but I'm not even aware if it has even been discussed.
I'd like to think that the platform is now mature and tuned enough that they could start to introduce some major new functionality rather than just keeping the lights on.
