The tbh app basically has you add your friends and then asks you questions like: who's really good at being a friend? You choose someone, and it tells them someone said it about them, but not who did. Anonymous compliments. One of the few apps I know which actually tries to create a positive vibe. It has a network problem, though; most people aren't on it. I wonder if a similar thing could work where your friends are those you follow and are followed by on Mastodon? Could be lovely.
@Tom4hawk Well, a number of reasons, in my opinion:
1. most friends don't actually compliment one another in detail very much because it's a bit embarrassing
2. if you think someone's great at something, you may not feel close enough to them to tell them that without it feeling creepy, even if you are acquainted
3. being complimented is nice. It's a good pick-me-up for someone to hear nice things about themselves without having to worry about ulterior motives
