Is there a way to search for a recent thread which you are unable to locate by the site or category search - it seems the 'All - questions' listing is not in chonological order, and it is sometimes of interest to go back to something that is just a bit older than 20 most recent questions.
By the way, is the site doing as well as you had hoped for, perhaps even better than that ?
Once a question's gone off the "20 most recent questions" list, it's gone forever, unless you are prepared to wander in cyberspace for many, many aeons.......
