That's a change of framework or the original contents were lost?
It's hard to value a Q2A site because most of the public questions are not well framed and unless we have a very dedicated site for a topic (then community size become small), Google search wint rate it high. Our site for example is dedicated to GATE examination and Google search performs well if one searches the actual question text but nothing if search is outside of this. We use this site for sharing our content with the needed users. Google ads pays for our site expenses- but can't even help us employ someone part time for content management or moderation. For this we rely on other services like exam subscription.
