One example can be resources and efficiency. One time I was trying to browse Google Fonts to find something in a certain visual style (ie not something you can really search for via keywords). It made Chrome completely unresponsive after a little while. This was a few years back so maybe it’s better now, but I’ve seen similar slowdown on other sites. A more human reason is that personally, I like to portion out and chunk off parts as no longer requiring my attention. I read a page and move on, clear the mental cache and start again. Infinite scrolls can mess with my focus.
