Also includes some examples of stuff that is ultimately irrelevant for reddit as a platform, such as canning and electric garage doors.

That stuff absolutely is relevant, because having the right info for those things is crucial, because acting on the wrong info can literally kill you.

The reason why Reddit content is valued so highly by users (and search engines) is because it was seen to have some level of curation to it, due to the efforts of the volunteer moderators who took their “job” seriously. They felt that it was vitally important to weed out dangerous info.
