I'm sure there's some SEO component, but I'm surprised no one mentioned ads.

More real estate for you to scroll through for display ads?

Point #3 from TFA mentions longer pages giving more space for ads.

I agree, though. It's why I try going to websites run by people who make their money elsewhere. Like Food Network.

Out of sight, out of mind, but they were mentioned a few times.
