A letter from Paper (FiftyThree) to Paper (Facebook)
People are going to call the app by Facebook "Facebook Paper" because "Paper" is simply too generic. 53's drawing app name is not strong either. Their iOS app is not called "Paper", but "Paper by FiftyThree". Their icon is not of paper, but of a napkin style rendering of "53". For all intents, the drawing simulation brand name is "FiftyThree". There was a brief moment in history when people thought "I wonder if 53 was acquired". That time has passed, and no one will mistake them from now on.<p>"Facebook Paper" is an alternative interface to Facebook.<p>"Paper by FiftyThree" is a drawing application.<p>Other than that they are both software, there's little room for confusion. 53 can get upset and write a blog post about it, but there is no substantive damage done. They'll probably sell more of their own product because of this.
