Thanks, you just made a good point and gave me pause to some up-voting. I never considered it. Sometimes I have an intuitive sense that some occasional mod-signalling exists. It least it has caught my attention. When I see it, it's like-- "WTH? That statement is banal and stale. Oh, it's a mod making the statement. I get it." On other thing you mentioned, I believe Peter Drucker talked about similar defense survival strategies in the work place. I think he referred to it as safety-in-numbers and pulling each other up the latter.
