True, but I've seen lots of answers that are "hacks" when there's usually a better, supported way that was spelled out in the docs, e.g. won't fail when you upgrade the library say.

Or they don't want to understand the issue at hand, so they put in a hack, when obtaining a complete understanding of the issue which might take 5 minutes of their time reading the docs, would provide a better solution.

Exactly. I code in half a dozen different languages that all have their own ways to split a string. When I can't remember the syntax to do this in, say, Python, being able to just say "python split string" and it goes to a reasonable SO answer is a big win for me.

I love reading docs too, so I can get a deeper understanding. But sometimes I just need an answer in a hurry.

Yes, people are lazy, most do not even learn from SO answers. They copy paste, move on, no greater understanding achieved.
