I bumped into this interesting site droppingknowledge.org, an open-source platform where the people across the globe can ask and answer quetions on subjects of their interests from pool of 25000 interconnected issues. Its worth spending a couple minutes on questions people have in their minds. Something as fundamental as "Why do educated women choose not to have children?", "why do men go to wars?", "Why me?" etc.

All of us have questions and no time to ask them, forget discussing and finding solutions. The least we could do is ask a question and let some learned men think about them.
