Hard to say, I'm sure it's high. For myself, I lurked here since the beginning of GFY and ultimately registered in 2005. But I lurked, and did business with GFY'ers up until that point, and continue to do so ever since.
The board dynamic has certainly changed in the last decade with seemingly more hobbyists and surfers than ever these days. Perhaps that perception of very little serious business being conducted these days, amongst an avalanche of non-business related threads, contributes to the lack of participation?
