Building a reputation is creating value for others. 

Being a crypto-native social network, "help others make money" is perhaps the easiest path (see Noice and Degen whales for examples), but it's not everything.

Outside of redistributing money, other ways you might be able to create value:
- building connection and friendship
- provoking someone to think a thought they never would have without you
- creating sardonic joy through clever memes
- network data visualization and meaningful critique
- writing a really thoughtful testimonial or review
- making a mini-app that others find fun
- doing a UX/UI breakdown of a mini-app and sending it to the founders
- etc

At the end of the day you can just do thing.
