The best Twitter app receieved an update last week, an update that added a button to the app's timelines to allow the user to only view tweets containing embeddable media.
In essence, this turns Twitter into a large image board. Unfortunately, treating Twitter as the world's largest image board makes it an incredibly unoriginal and repetitive place. As image boards go, Twitter is terrible.
But if you want to quickly see a stream of cats and other memes, hit that button and go for your life.
