There is a huge downside lurking even beyond the reasonable critiques already made. The posts this week would have had Obama v Blah v MidEast v Israel v Iran v Godwin.
There are plenty monks here with whom I would have violent and probably acrimonious disagreements if we opened the gates to politics, philosophy, etc. And since I have a low tolerance for that, even being on the sidelines, I'd just leave. While the topics remain Perl(ish) I can respect and even admire these same persons. It's quite stabilizing. I don't visit other forums for pretty much this reason. They don't specialize enough and the signal to noise on almost all I've seen or tired is not good enough. Viva la PM!
