How I did it: I guess I simply asked some random questions everyday. Almost everything that crossed my mind. I know that it's in the human nature to like to answer questions. It's a matter of pride, people like to talk about theirselves. So I gave them an opportunity. And I played too, answering other people's questions. And I still do.
