What I like is that there's always someone on here who's a legit expert on any subject imaginable. Like someone can post a pic of an obscure tape drive from the 60s and almost instantly someone can tell you all about it.

Or a rigorous back and forth on the horse-riding tribes who spawned the Indo-European languages.

Or people can put in context some outlandish quantum computing headline in a way that you'd never get from the actual article.

That stuff is valuable.
