|The stupid question is the question not asked|
"We do not know how many people feel that they dare not post here."
Since you don't know you're just scaremongering?
"We do see threads opened-up by newbies with an opening request ... even before they state their business ... of please donít pillory me for asking."
This happens with relative frequency on many Q&A sites that I've seen.
"How many others never get that far?"
There is no way to tell. Why postulate?
"knowing that they will be welcomed here in addition to speedily getting the best possible technical answer"
Given your frequently posted technical inaccuracies, code which doesn't work or blatant nonsense (technical or otherwise) how can you make such claims? In addition you've berated people for having the audacity to share their work or experiences! (one example)
"This web site should be a social place"
I think it's fair to say you've got a track record of antisocial behaviour here, and this entire post seems to be another 'do as I say, not as I do' post. How are you making a positive difference here?
