While I find Stack Overflow very useful, I find it's model very restrictive.

Sometimes you can get more insight on how to solve a problem from a discussion than from an answer. Why and when can be as important as how.

Also, if people dislike your question, even it obeys the rules, it gets down voted. They can dislike your question because they dislike the problem you are going to solve or the way you are trying to do it.

Some comments instead of being related to the question at hand, suggest that you shouldn't solve your problem but instead do things another way. Which can be fine, but doesn't fit well the site format because it doesn't allow discussions.

However, I don't see alternatives. You can ask on reddit but there are not many people willing to answer.

If you're lucky, your language/library/etc might have a fairly active IRC channel or similar. Popular languages often have a myriad of channels dedicated to different subtopics.

They're nice because like you said, discussion can be much more helpful than a single answer.

Great suggestion.

However, one issue I've run into with the rise of chat and SO, and removal of forums, is that if your question isn't the right fit for SO, and is a bit tricky/time consuming, it's easy for your query to be buried.

I reached out to the TypeScript community via Discord about assistance on how one would add TypeScript definitions to an existing JS repo. Got a little discussion, IIRC, and then because of other factors, was buried.

For math, I like math.stackexchange.com.
