I don't claim to have all of the answers, but a decay function seems quite obvious to me. For one thing, technology evolves. The jquery way of doing something shouldn't have 10x the upvotes as the ES6 way. Old answers should lose a percentage of their upvotes over time, if they remain relevant they will gain new upvotes, but if not, they will get surpassed by newer, more relevant responses.
Oh, and the new fonts.
I didn't even bother fixing my question. I deleted all my stack exchange accounts.
Open SO, choose any popular tag and just wait. In a hour you will see a dozen of "do homework for me", "what's wrong with my code" and "explain this very basic thing to me eli5". Not to mention things explained in introductory lessons of any decent tutorial or things answered by first search result.
Not to mention bad grammar and even worse formatting.
Minimal, reproducible example is just a dream.
StackOverflow users are constantly complaining about duplicate questions. The real problem is that the onus for better question asking is placed on the asker, who is only really motivated and prepared to express their confusion.
The whole reason most questions are asked is because the asker isn't familiar enough with the problem domain to find the answer. That also means they aren't familiar enough with the problem domain to find a duplicate/related question.
It's much easier for question answerers to find duplicate and related discussion. Instead of antagonizing the asker by closing their post as "pointless discussion that has already happened", answerers should be continuing discussion with the asker.
Every StackOverflow question (duplicate or not) provides two opportunities:
1. Answering the question.
2. Finding what information to better advertise so that confusion can be avoided in there future.
Also it’s a trope that the select answer isn’t always the best so there is a meta conversation about what is the “really best” answer
I have spent time responding to questions on Stackoverflow, I think I spent 2-3 years providing answeers, and one time I answered a question that didn't follow a weird policy that I strongly don't agree with (https://meta.stackoverflow.com/questions/311442/opinion-base...). I got banned, and my account has been deleted, the answers still there. My only regret was that I could have spent that energy and drive to contribute to open source projects on github. Now, I have less time, but I answer questions -when I have time- on reddit or forums.
"Hot Network Questions" are a distraction and take up too much horizontal space.
It really seems no one is there to help each other. It's mostly status quo or reputation. Moderators have too much work to do or have serious ego problems (most users call them "StackOverlords"). Or a mix between the two.
One thing I noticed is that other sites of the Stack Exchange Network are doing quite well. Probably they should split up SO, at least with one site for backend related questions and one for frontend, or even for specific frameworks/platforms. But this would also split the value of the site, so I don't think it's gonna happen.
Eventually someone will disrupt the whole network, just like they did with Experts-Exchange.
Having massive amounts of questions gets more surface area for ads but a lot of programming Q&A that is a few years out of date is mostly useless. API's change, things become deprecated or better solutions emerge.
They need to cull massive amounts of content for it to be more helpful but that would likely drop revenue.
The only even mildly negative experience I’ve had was once a high-level user pattern-matched one of my questions to a much simpler already-answered question and closed it along with a dismissive comment, but as soon as I commented highlighting the discrepancy he apologized and answered my question.
On the rare occasions I find a useful question, some asshole closes it because it was asked before. What makes them an asshole is that it's not the same question at all, or the question was not answered.
2. Why aren't answers always sorted by the number of votes by default?
3. The "community edits" where people sometimes decrease the quality of an answer just to get points.
4. Some answers don't age well but they are perpetuated by their large vote count.
2> You didn't ask the question in the right way, or are on the wrong platform, OS version, etc.
3> The tons and tons of ads.
The best thing about reddit (imo) is being able to search for a question, and see how the solution the community came up with evolved over time.
Questions closed as duplicate when there is some subtle but important difference.
Closed questions still appearing in the search results.
Mostly though just a general lack of good will, it's obnoxious.
