The structure of Stack Overflow is designed to get question and answer pairs that contain the critical information and are easily discoverable by google.

Questions and answers that have value and that follow that model are likely to be more discovered by people using Google.

There are many people who consider all social media sites to be "the same" - basically posting whatever they want. Be it forums and facebook or whatever random idea hits your mind on Quora. Those are different models and work for different types of problems. An asynchronous debugging session likely works better on a more forum like site than Stack Overflow... and yet people post such questions to Stack Overflow. When those questions are found, the people who are entrusted with the various community moderation privileges, in an attempt to follow those ideas of "This site is all about getting answers. It's not a discussion forum. There's no chit-chat." (from the tour) will use those moderation tools to try to make the good stuff more findable and the stuff that makes the good stuff harder to find... well... gone.

There are many different sites out there that have different focuses. Stack Overflow (and the model the rest of the Stack Exchange sites use) is trying for one narrow slice that they can do well. People that want a forum should look to a forum... those who want to ask for opinions and anecdotes should look to sites that do that better. Stack Overflow is not intended or designed to be the be all and end all of software questions.

Thanks for the reply, but this doesn't explain why correcting answers is so frowned-upon. Or a general hostility in tone from the mods.

No worries. I find that in practice the kinds of questions that I can't answer for myself (the kinds for which a natural language question rather than a straight Google search for documentation is helpful) are almost always already answered anyway. So having it a read-only site is not a big deal.

I think their model does indeed turn away a lot of people with good experience and intentions, and even leaves a lot of incorrect cruft lying around, but overall it's a mostly-beneficial source of information, with, as you say, high searchability.

First note - "mods" - only the people who have a diamond after their name are mods - https://stackoverflow.com/users?tab=moderators - its a rather small group.

Everyone on the site who has 15 reputation or more can participate in community moderation to some degree or another. There are people within that community who use the community moderation tools of voting frequently in an effort to have the site match their vision of what it should be... but they aren't mods.

When dealing with thousands of questions per day (90% of which are crap https://en.wikipedia.org/wiki/Sturgeon%27s_law ), the amount of time they have to work with any one post is very limited. Often people are terse in their comments - it takes time to sit down and write a thought out reply... and that is very limited in comments if it isn't an answer itself (and to that point, that is by design).

This terseness of communication is often interpreted as rude. Its not intended to be - its just the medium and limitations. Yes, sometimes people are rude. The thing to do in these cases is flag the comment as rude - if there is a pattern with the behavior, the moderators (with a diamond) handle the flag and will take it up with the user who is rude. Saying that your code does not work as described in the question, however, isn't rude.

I applaud your use of google first. There are so many people who fail to realize that the goal of Stack Overflow is exactly for people like you - who search with google and find an answer and never need to ask a question on the site themselves.

The significant amount of incorrect cruft laying around is a side effect of people not using the moderation tools (downvotes on questions can make the questions get deleted and make search results better) or a value proposition that has entered the collective community moderation of "anything that attempts to answer the question has value and shouldn't be deleted." Unfortunately, that later point reduces the value proposition of the site and diminishes its utility.
