I could be wrong, but I think Scott Williams had the first free Mac support site. Originally named 'Appleboy', and later changed the name to Nowonder.com. This was years ago, and the site grew rapidly. Thousands of questions answered each year, the last year Scott had it, had to be close to or over 40,000 questions answered. if Scott comes along, he could post the figures.
There are some past techs from Nowonder here on Macosx.com, including myself.
