I had avoided getting into this, but then I could never keep quiet anyway. So here is my tuppence worth (inflation adjusted).
One of the things that keeps me in this group is the wide spectrum of knowledge that is available here. And the fact that often, the most controversial of topics can and are discussed here, without it descending into acrimony. I truly believe that the members here have a healthy respect for one another and that even if we might disagree on certain matters, that respect doesn't wane. I doubt if there are too many such groups on the net or even in our "real" life where one could discuss anything under the sun without fear of offending someone's sensitivities. Hence, I am all for discussing anything here :)
