I think that both major mobile platforms need to revamp their photo flows to adapt to all the buckets mentioned in this article, along with a "private" bucket for things like naked photos and other pictures not everyone would want automatically "shared" onto a feed (Apple has dipped a toe in this water with the "hidden" flag on photos, but there is still a long way to go). And while I'm wishing, I would hope that they do all this while still allowing for automatic cloud storage and backup without compromising privacy.

It seems one of the main reasons Snapchat is so successful is that it provides a flow for photos and other communication that isn't the traditional "single stream that also doubles a permanent and mostly public record" style of organization. It seems inevitable that iOS & Android will both have to eventually adjust their built-in camera & photo handling apps to acknowledge the realties of how people actually use their devices in this regard.
