I’ve been coming here less than a month, but my experience so far is that people that have gotten to know one another are quite supportive of each other and I like the way people tend to thank others for good contributions to their questions.
I don’t think there’s a ‘touchy feely’ culture on here, but at the same time, doesn’t take long to realise that positive reinforcement doesn’t cost you anything and it’s unlikely to be moderated. The opposite is, well, opposite.
Personally I think the atmosphere is great and I’ve taken it as a good sign that people occasionally leave a kudos comment, using personal comments, but so far I haven’t received any vicious private comments….those have been kept to the threads. Considering that’s the public domain and subject to moderators, I’d say that’s a sign of an overall positive ‘collective’
