Why is there almost no website that use right and left arrows to navigate?

I was reading this article: SFW click-bait!

This is a classic click-bait article where the user where the reader has to go through multiple pages in hope to get some interesting information. This kind of site is irritating to everybody, as one has to click on a "next" button to go to the next page, and this button is often buried in a block of advertisement (this site's very purpose).

The page I link is special in that one can change page using the right and left arrow.

Why isn't this feature more common?
