Thanks for sharing your thoughts @edje, i believe that their is a room for improvement in any technology and i really like the idea behind this app where real peoples answer your question through private chat.
Once you type the question and hit search superfy won't select any random user infact it do it's own research and refer you to a person that will give you a best possible answer and it's free so their is nothing to lose.
As far as privacy is concerned you can use this service anonymously without signing in through your real facebook profile.
