That was my initial thoughts when Relay/GraphQL were announced, but it seems that though Relay is inspired by Flux it is somewhat different. Facebook's most recent post on Relay and GraphQL (http://facebook.github.io/react/blog/2015/02/20/introducing-... - February 20) addresses Relay's relation to Flux at the end and mentions that Facebook actually has apps using Flux and Relay.
This is a great idea, but I'd be concerned that a bunch of the users would freak out when they were told that Facebook checked whether their current password has been compromised. Anyone know how they word the notice to the users to keep non-techie people from getting concerned that Facebook is looking at their passwords?
BTW it isn't very clear how to download the apps - took a couple minutes to figure out that you had to click those litte icons on the home page and when you are logged in you have no way of knowing.
