@PepperTheVixen That makes me confused too.
I also remember the lectures people gave newcomers that "favourites are useless" — apparently that became a meme to do because Twitter had changed others' likes to be visible/notifiable events a couple years earlier, and everyone apparently forgot that for like 10 years Twitter did not operate like that. Likes were likes (announced to the poster), and retweets were retweets (announced to your followers). As they should be.
There was absolutely no point in discouraging people from favouriting things. It's excellent feedback for the poster!
