libraries are curated, organized, and structured to allow browsing.
random does nothing of the above.
meaning is a polyspectral space, and libraries are a lower-dimensional reduction of that to allow perusal through multiple bands of meaning. while the result may be arbitrary, it's within the bounds of the arc in the meaning-space. In addition, the curation of books means that arrant nonsense is culled (hello r/ooer), and highly niche bits of meaning are stored in appropriate places - usually residing in academic journals housed in university libraries.
Libraries.... are not precisely tiny. Depends on the library. And a shocking amount of internet statements have a shockingly small entropy.....
I’d easily put this in the top three reasons I stay in this job.
I consider clicking the random link on Reddit analogous to firing a gun into a bookstore, or randomly flipping channels on a TV: no discernment whatsoever, and very shallow, very often completely worthless results. 99% of the time I click random on Reddit, it comes up with complete garbage, IMHO, to the point I don't use it anymore. Meanwhile, the best subreddits I've come across have been "curated" by recommendations.
You mean like the "Random" links on Wikipedia and Reddit?
