I’m yet to encounter the majority of issues I hear Lemmings griping about. Everyone has been pretty civil toward me. Every time my inbox blows up I feel dread, only to open it and find zero confrontation or vitriol. I’m not running into any racists, sexists, bigots, etc., and I certainly haven’t noticed a decline in content (I browse Top ~6 Hours).
I realize my personal experience doesn’t equate to these problems not existing, but I do get the strong impression that people are exaggerating greatly.
