What we really need is an intermediary. The people who develop crypto primitives are currently too far removed from the people who develop consumer apps (obviously excepting guys like 'moxie), and (rightly or wrongly) the majority of consumer app developers don't know how or don't care about bridging the gap. A central key repository with de-centralized identity proofing like keybase would be an interesting idea if it had a good developer API (which I assume is in the works) and if good cross-platform PGP libraries existed (a bit trickier... GPG is not iOS-friendly and any lib which ignores that market is not serious about being accessible to consumers). So, in other words, keybase could be a valuable and important step toward a "mom friendly" system, but it's a bit early to say.
