Most, if not all the members that regularly post on this site have met each other in real life, and i guess would on the whole consider each other friends.
I pointed out to a few new members on the VOD, they come along not realising that a lot of people know each other, and talk to each other on the forum, rather than just communicating on the forum, with no other contact.
So far, most the regular posters here, are not going to get overly controversial.
I think some new members come on the VOD, and want to make an impression, try to be clever and show what good ideas they have, without realising that there is more to it than just the discussion.
