Proposal: Stack Overflow (in Spanish)
So, this is my question. Maybe it has a technical reason, that the language support somehow avoided a 100% area51-based site creation process?
It's not quite a working site. Work surrounding getting the translations done was mostly coordinated in chat; they reached the point where they really need a meta site to continue at the same awesome pace of progress. Questions like which words should we use also need to be part of meta, as these answer questions that folks in the beta will be likely to have.
There also comes a point in a new international site where we have to stand it up on the public tier and test, test, test.
Juan will be contacting committers to the proposal to let them know the launch schedule in the very near future, worry not. And if you missed committing to the proposal, that's fine - you'll still be able to join following the link from Area 51 once it works.
tl;dr - It's "public" like a building still under construction, closed until some final finishing touches take place.
