"Are there any [lang] libraries that are backings for the [service] API?"

This is explicitly listed as off-topic:

Questions asking us to recommend or find a book, tool, "software library, tutorial or other off-site resource are off-topic for Stack Overflow as they tend to attract opinionated answers and spam. Instead, describe the problem and what has been done so far to solve it."

And this is precisely why I left SO. Without fail, the most interesting and useful questions for me on the site were more or less surveys of the population -- "What's a good library for reading XML in C#?", "XYZ looks like it was abandoned, is there a good replacement?", "Why is Python 3's virtualenv different" and that kind of thing.

Maybe that's just me, because if there ever is a question with one correct technical answer, it's easy to figure out on your own. The things I want to interact with a human to figure out are universally to do with historical reasons for things, ergonomic choices, and opinions on quality. I want a smart person with strong opinions, not a politically correct karma grinder who can type quickly.

I disagree. The question does not ask to find a library but rather it asks about the internal workings of a service.
