We ended promoting our own Questions area a few months ago. They just never took off. Instead, we've returned to our roots and posted snippets of news and rumors. Facebook Questions never took off either. Now it's officially end of life. TechCrunch opined Questions was to be a Quora killer but the ecosystem never accepted the product from Facebook. Whatever the reason, it's a good reason - because Crowd-sourcing is challenging on the web. People can easily open multiple browser tabs and pretend to be different people. Trust and verifiability is something that is just not a strength of the Internet.
