It's apparently a website designed for the asking and answering of questions, in which a ranking system is used to place answers to posted questions in order of popularity (?), presumably such that the best answers (hopefully the most accurate) rise up the rankings to the positions where people will see them.
Sounds interesting, but I'm always cautious about downloading apps to my tablet that I have no recommendation for, hence this posting.
Any observations would be gratefully received.
