I noticed Why is C++ still a very popular language in quantitative finance? was protected, presumably to stop a language war. I just wanted to point out that if you have another worthwhile Stack Overflow account you get 100 reputation just for joining.
So when the intention is to limit answers to "Quantitative Finance" regulars, maybe the minimum needs to be over 100?
(Having said that, the discussion I quoted seems to have been okay, so that might be overdoing the policing?)
