These are great rationale, but I think they belong in the feature marketing and UI, not just the FAQ.
As publicized (by Keybase and every other platform), exploding messages appear to put control of post-receipt management in the hand of the sender. This is especially credible coming from Keybase, since you guys are educating a lot of people about possibilities with careful crypto (e.g. forward secrecy). This has risks... you mention the Snapchat user who was protected from bullying, but what about the teen who wouldn't have sent that pic in the first place but felt safer because of SnapChat -- only to be bullied over a screenshot anyway?
Your description here is that exploding messages make it easier for both sides to announce and abide by a social contract about deletion. A name like "flag messages for auto-delete" (I'm sure someone can do better) would set the right impression.
