I think there are a lot of pilots (just a hunch not a fact) that come to this forum and read but don't necessarily post. I for one rarely post but I do keep up to date and view a lot. I personally know of quite a few that lurk and never post. There is a lot of good info here and a lot of not so good info. Just because the number of active/prolific posters might be a small number/percentage, there are a lot of readers/lurkers. Just look at the number of views vs posters.
