No matter how much we try to put ourselves into a mobile first mentality, it is hard for us to do so fully. Our access to PCs prevents us from experiencing mobile the way many in the world do.
We're currently fighting for parity among experiences. We're arguing that the mobile version shouldn't be a dumbed down version of the desktop site.
But we've set our sights too low. In a true Mobile First world, the mobile version should be the best experience. Mobile shouldn't just match the desktop experience, it should exceed it.
