I remember I read in HN somewhere that, people _want_ to feel useful in code reviews and one way is to leave comments. So one strategy is to send stuff out early with some small imperfections so that people who want to feel useful can pick on them. IMO, following this spirit, and in this case, an efficient but not necessarily personally beneficial strategy would be send out a PR early (so that you're not investing in too much time and not too emotionally invested in defending your solution later), then get them to suggest solutions, and implement in their way. This takes away pretty much all of the pleasure of creation in coding and deprives one of the sense of accomplishment, but it's far less frustrating and mentally straining than having to argue and defend which solution to adopt, to me, when working with that kind of people.

Were they any better at finding edge cases or was their non-nitpicking feedback particularly insightful?
