Sure being more welcoming to outside contributors sounds good. Do you have any concrete suggestions how to recruit and train them? We do have some community contributors, but they seem very limited by the amount of time they have for Lemmy after their fulltime job.
Once the new round of NLnet funding is finalized we will publish those milestones. However Im not sure if a backlog like the one you linked is really helpful, it would take a significant amount of time to manage for little benefit. After all every open issue on the Lemmy Github is up for grabs for anyone to implement it.
Hmm not sure whats the context of that quote.
