I definitely curate what I upload to pretty much the same degree as I did for "slide shows." But I've long wished for a "gallery stream" that let me flag the photos I really want to show off versus those I want to retain for myself.

(And in so doing, serve as a really worst case backup although my raw files are backed up in a few different ways.
