> perhaps I should just view nightly as any other language's "stable". It depends on the features you enable. Stable is basically just a pinned nightly version with no features enabled, and I'd definitely view "nightly with no features" as more stable than most languages. Using some of the more experimental features would make it less stable, you can generally get a feel for how stable a feature is by looking at it's tracking issue. These days most tutorials/books/tools don't seem to use nightly in my experience, though many still do. But if you're primarily looking at blog posts that are pushing the boundaries of the language (e.g. by writing operating systems) I expect that most of them would be using nightly.
