So, there's this thing called Formspring. Apparently it's really big, yet many people have never heard of it. Here's the gist: you ask people questions, they answer you. In turn, people ask you questions and you answer them. Sounds exhilarating, no? You can get questions from users you know, users you may not know, or anonymous questions (that's where it gets... fun).
Now this Formspring thing is native on Android.
