I keep seeing lots of long-time #fediverse users saying 'don't favourite posts it does nothing' but actually when you favourite my posts it makes me smile and I'm sure I'm not the only one.
@djdellamorte i feel like fav'ing is a really nice little text-based way to gently communicate approval or affection or interest. 'this makes me smile' and 'i wanna think more on this' and 'love this for u!' are pretty useful ideas to express.
