Entirely agree Rob. There are things I have decided not to post - not because I am 'timid' but because there just isn't any point as the likelihood is that the aspect I think may be interesting to people will be drowned out by the pointless noise. I can see exactly why some people would decide it just wasn't worth the time and effort.
The brilliant thing about this forum is that it manages to combine 'ask the expert', be that on fungi, chainsaws or 'my tree is doing something odd', with high level technical discussion between experts in their field, as well as being a place for relaxed chat between people with shared interests who know one another, sometimes in person as well as through the forum, and probably some other positive things as well.
The relaxed chat, ie entertainment, inherently includes an element of friendly banter, but you can spot this easily - it's the running jokes, lots of emoticons and general good humour. As a newcomer, you may not get the joke, but you can see it is around you, not aimed 'at' you, and maybe you even feel more involved by it - it suggests that this is a friendly community to be part of. There are also some pretty heated debates from time to time, based on strongly held but differing views, but again quite legitimate.
The trouble seems to be that a small number of members seem determined to pick holes or make personal attacks on the slightest weakness. This is not done in jest, but seems to be solely for their entertainment. At best this is unpleasant and a negative reflection on the individual and, as Steve recently pointed out in closing the ppe thread, by association, the forum. At worst it is bullying, aggressive and, recently, could be taken as sexual harrassment. There is absolutely no need for this and I for one would rather see fewer of these individuals remaining on the forum, hopefully to be replaced by more of the people Rob refers to above (and I have met others) coming back out of the woodwork and deciding that it is worthwhile to post, since I am sure they would add infinitely more value than the pointless posts of the current irritating minority do.
