It will be interesting to see how the "Needs Focus" close reason gets implemented by the community. I've seen a lot of open-ended questions that included 5+ questions in one post. This could be problematic when migrating those posts to the new format. Not a deal-breaker, in my opinion, but asking more than one question was even common in regular Q&A posts. Closing questions as "needing focus" was another pain point for newcomers.
However, I'm not against closing open-ended questions as needing focus. It's difficult to chip in an answer when the OP is going in so many different directions; their focus helps my focus, which helps me answer their question.
To us long-time members: please, please, please, please, please be patient with people. If a traditional Q&A is better suited as one of the OEQ types, just change the tags. Post a friendly comment explaining why you made the change, and don't sweat it.
One of the most frequent complaints I've read (and directly heard from people) is that we moderate (down-vote, close, and delete) posts WAY too fast. Remember that we all have fulltime jobs outside of posting on Stack Overflow. We live in every time zone. Some of us work a Monday-Friday schedule. Some of us don't. People can take over a day to respond, maybe more, and still not abandon their posts.
