Literature is often a window into subjects the reader might not have been exposed to before, or will ever be exposed to.
Many writers on this site have put out pieces that are thought-provoking, mind-bending, and/or otherwise remote to someone who’s grown up living under a bubble-encased rock.
These, among many others, stand out most prominently in my mind:
illusionistic has portrayed interesting forsight in sci-fi and entertainingly thoughtful insight on other subjects. The latter I have not had any experience at all, but illusionistic has written about them with such ease that it doesn’t exclude the rather naive outsider (i.e. yours truly).
Stovohobo. Honestly, I don’t think I’ve ever been disappointed by something by Stovo. All thought-provoking from someone wise beyond his years.

Thank you illusionistic, and thank you Stovohobo.
