So I’ve been using FB’s new Paper app. It’s a different kind of FB experience IMHO and I don’t see it replacing the FB app many is used to however glowing the reviews are coming in from tech blogs.
The plus the of the app is it’s magazine-like interface so news discovery is wonderful and I love the page flip effect (similar to FlipBoard only vertical). The minus of the app is it makes fast scanning or scrolling of friends posts difficult (almost impossible actually) especially with the use of tiny fonts on preview panels.
Ultimately it really depends on what you want Facebook to be for you. I think it’s great that Facebook users can get two vastly different experiences from two different apps yet staying within the same content stream.
