Am I alone in thinking that it would be confusing and unnecessary to have a "save for later" feature in the form of "favourite" as well as "save for later" in the form of "bookmark" side by side? 
@Gargron I'm firmly in the camp of those who would like the two separated. I'd like to be able to give people affirmation by favouriting (or better, liking, because favourite is too extreme) their posts and I'd like to separately save some things to read for later.
@Gargron The first one, liking, is by nature public. Saving or bookmarking for later reading is I think something one can do privately.
