Proposal: Legislative Innovation
As Tim Post stated2 "In order for us to consider a localized site other than Stack Overflow, Stack Overflow must currently exist in the target language." There is a stack overflow in portuguese, so let's advance to the next requirement which is "we positively must have community manager cycles to spare, from someone fluent in the target language".
That second requirement is a problem because we can't possibly know when and if there will be an available community manager. I also wonder if they're even hiring.
So we probably won't get this Q&A site created but I took my time to translate the proposal to english and write this because I think that it will be nice to advance to the commited stage and maybe then, after we demonstrate engagement from the community the Stack Exchange staff will consider launching our site to the beta.
