Poor analysis by some of the users (there are a lot of non-technical commenters on here) doesn't negate the higher degree of technical discussion that has indeed been present here. Just because opinion and fallacious arguments are present doesn't mean that good technical discussion isn't. Outside of dedicated infosec communities, I am not sure what online community has had more purely technical discussion on these issues over time. Feel free to list them though, because without sarcasm, I would be happy to know of them.
