So, for those of you who have just moved over from Twitter, I've been learning that a "favorite" over here is just a pat on the head to the author. It's not like Twitter which moves liked tweets onto other people's timelines & gives them reach. Boosting, however, does some real good in that it improves the reach of the tweet. If you think others may be interested in something you read, boost it! There is no dreaded algorithm, so the only way to improve reach is a boost.
