Facebook is about displaying posts in descending order. This screenshot is way to confusing. It's too hard to follow posts. It may work for, say, Pinterest but it wouldn't work for Twitter and Facebook.

"it still works fine" is rather subjective. I much prefer Facebook's current and last design, from both a usability and aesthetic view.

Hey, that's not crap. It's herp herp.

Lol at least it will confuse grandma
