"What do YOU think makes this site different from other Q&A sites?"
Why, at one time, I was one of the highest ranked volunteer 'experts' on the site, having amassed the EE equivalent of a zillion karma, or whatever they're called, and then, literally, the first time I go there to ask a question, they're all of a sudden premium? I literally helped build that site's content, and not only got nothing for it, but I have to pay to see the answers that I populated the site with?
