I just released (hours ago) a new reading app called FYP. It provides you with a shareable link your peers can use to share links with you. It's built almost completely on Google's Cloud Messaging platform, so links shared with you are sent directly from a go server to your phones local storage.
Motivation for FYP came from me receiving lot's of links to videos/articles/etc and either 1) losing them in the noise of my day-to-day communication, or 2) feeling the odd pressure of needing to respond back to the person who sent it.
