It let's you post a bounty for any feature you want to be implemented. When feature ships, author of the code receives raised bounty. It can be anyone, not just Prismo team member! :)
Good news - yesterday i managed to implement a federated comments! We're getting really close to first official release ?
Meanwhile - did you know you can have a real impact on development process (without having the programming skills) by joining our discourse forum and taking the floor? https://socialhub.network/c/projects/prismo
Just a tiny update: i'm not working on Prismo atm because i'm actively looking for a new job (btw: if your company is looking for ruby on rails / vue developer, let me know! :D)
Last thing i did was a fully functional activitypub voting. Next thing is gonna be an AP commenting and Prismo is ready for it's first official instance deployed.
