> I think it's awesome. It sets a public precedent for kind behavior and appreciative attitudes. It always makes me happy to see people thanking each other in that chat.
Which brings exactly the same problem as the likes: some people always appear on those chats, some people never do. Does that mean that they are doing a bad job? No... they just get less visibility.
How do you get more visibility on the "gratitude" chat? By thanking the others, so that they see you more and think about thanking you in return, I suppose? In my experience, some teams keep congratulating themselves, some don't, at all. And management sees those who are visible, even if it is not fair.
It can quickly get artificial, and a bit depressing for the people who don't really appear there.
