The most voted question on this site is locked because its opinion bait. Why vote at all if questions must be answerable with a short blurb of facts?
What is the value or lure of seeing or voting on the answers 4, 5, or 2 to the question of "1 + 2 = " ? That is basically how the site is currently set up which results in the most voted question becomes closed. Google is already answering these types of questions automatically. It doesn't take many answers or much research to come to a good solution for these types of questions.
The original site was for software questions where there is no single factually correct answer and is normally answerable with many good and bad solutions of which some may even be incorrect. With each input/answer you get a partial solution that when put together can be a powerful and efficient solution.
That doesnt sound like a model for simple fact based question and answer blurbs. Instead sounds like opinion bait that uses opinions (ie votes) to decide which ones are the best. Whats up with that?
BTW, the most useful answer I got here was an opinion bait question that I thought would be closed for sure :)
