Brian Lovin writes about the design details of Facebook Paper:
Paper by Facebook has been out for a day now and the reviews are, for the most part, quite divided. I haven’t been an avid Facebook user for some time, but the design and attention to detail on Paper is unmatched, and is worth sharing with other designers.
I do agree that Facebook Paper is exquisitely designed, and Lovin points out details that I missed. That said, despite the utmost respect I have for Mike Matas's design acumen, I've found Facebook Paper to be really inaccessible. The thumbnails are hard to read, buttons are small, and VoiceOver support is horrid. It's too bad, because Paper is so beautiful, but it's not very usable if you are blind or have low vision.
