I don't remember, I must have heard it from someone/people who were on a previous social Q&A website. But that would have been before Retrospring went down for a year or a few and then came back. I don't remember how I heard it came back, I must have been in outside contact with a Retrospring user. Either way, Retrospring is the last of a long succession of social Q&A sites I've been on that kept shutting down, I think this is the reason a lot of Retrospringers are here. The first social Q&A site I was on was before spring.me, I can't remember what it was called, and I was on it because my friend Darin was answering questions on it and I'm always fascinated by what he has to say. http://facebook.com/darinstevenson
