I have a couple of GameFAQs discussions and cheat lists for various PS2/GameCube games from the early 2000s. They're stowed in a folder because it was a hassle to run between the family room and my bedroom when referencing.
Also, for the longest time, a household shared a single computer. So printing off the pages meant I didn't need to compete between family members for computer use.
Edit: A friend just reminded me of navigating in the passenger seat with a stack of Mapquest prints.
Edit-2: If anyone wants to relive this in the modern world, print to PDF blog posts, news articles, etc., and store them on your Kindle (or equivalent). You'll notice you'll comprehend the article way better than on your phone or laptop.
