Favorites saves them as a favorite. Unless I'm going to want to see that tweet again in the future I don't generally hit the favorite button.

If I think it's entertaining I'll boost it for other people to see. There's no algorithm sorting things by engagement, so favoriting doesn't expand visibilty on boosting does that.

Reddit had r4r communities, are we calling our communities L4Ls?

Didn't see a better place to ask this question.
