I don't know much about Patchwork ... what sort of value does it add? But I don't think much of the idea of delegation. I don't see a thriving developer community full of people who want work delegated to them. Rather I see a thriving developer community of people who see problems and want to fix them and dive in and do stuff. An apprentice who needs to have stuff delegated to them will always be an apprentice. A master starts by doing the things their master doesn't want to do, then moves to the things the master didn't think to do and finally blossoms by doing the things their master didn't know how to do. > > The hardest part about maintenance is taste, and md has been thriving > on good-taste pragmatic decisions for a while now. Taste is learnt by practise. Having someone correct - or at least highlight - your mistakes is important, but making the mistakes in the first place is vital. I think the starting point is simply to do. Read the code, ask a question, suggest a design, send a patch, pick a task of the road-map (or make one up your self) and start work on it. NeilBrown
