We would love to be able to give credits and rewards and badges to our users. Similar to the outdated Awards (Karma) app, where you get points based on activity and user events in Confluence (early/late login, creating, liking, commenting, receiving likes etc). Additionally users can credit other users with badges.
There are scorecards and user profile related overviews of earned points and badges. The basic idea of this addon is great, but it is not updated for a while and it has to include Linchpin content obviously :)
