Hi all, occasionally, in my free time, I browse hacker news, specifically, new posts, and quite often I see links to wikipedia articles, something remotely on topic, but often not. Today there's a link to [Third place](https://en.wikipedia.org/wiki/Third_place) and [Dark Matter](https://en.wikipedia.org/wiki/Dark_matter) and I'm always very confused as to what they are doing here, like why are people posting them?
