@smokey @manton @walter I'll take this opportunity to restate my wish for private likes. Like @walter, I often want to acknowledge someone's post. The problem with using an emoji or one-word reply is that it clutters up everyone else's timelines with a stream of đź‘Ťs or "Right on!"s replying to posts they may or may not have seen. I sometimes see entire screens full of one person replying to a dozen or more posts with not much more than "Nice!".
Receiving Likes feels good. They only become a problem when they are publicly displayed and tallied.
So, my suggestion is to let me like a post, but only announce it to the recipient.
