Should Stack Exchange cooperate with Quora, migrating SO questions that were deleted as off-topic or subjective, but are much loved and useful, to their site in a concerted effort? Along with the answers and maybe even comments and votes, if feasible.
I mean both popular fun content as found on the popular deleted questions list, but also some of the more substantial programming questions that were deleted, or have a historical lock now on SO. To pick an example entirely at random (being mine, I remember it well), I asked a question about OOP in PHP once that has useful answers (IMO) but was closed, and would have been deleted had I not flagged it for a historical lock.
Quora explicitly welcomes these kinds of subjective-y questions, so for those the format would suit perfectly. Stack Exchange doesn't want them and won't build an archive for them (for good reasons I guess.) Quora may be a competitor in the general Q&A market, but their model is so fundamentally different, I don't see how this would hurt Stack Exchange's business in any way.
Seeing as these days, new questions like that usually don't make it long, this would probably be a one-time effort, maybe with the Community suggesting the questions.
Of course, this requires that Quora actually want the content. I'm not an intimate expert in how their model works, I only understand the general concept and occasionally read through Q&A there.
