I adore wikipedia and my favourite part of the articles is the references and external links list. a deeper dive into the subject/topic. they always include research papers as well! love it so much.
not sure how everyone else engages with this site, but since i was a kid my brother and i would just have a bunch of tabs opened from various Wikipedia articles that sparked our interest. even today, we sometimes FaceTime and go through lists of [random category] just for the heck of it 😂
