It won’t be Reddit’s content but managing either the karma or native tipping they might want to do! It’s probably just an overlay feature to compliment their current system
It is a total buzzword and I don’t see why a centralized site would want users to tip or transfer capital Unless they are taking a feee
It does however makes sense if want to do more monetization features like closed communities and subscription and all that and take a fee instead of trying to build their own tokenomics which has been so far quite the stuff up for many projects
