I'm not 100% clear if you're looking for a pro crypto currency community that has thoughtful technical discussions OR a community that is more focused about being skeptical of crypto currency. I don't know of anywhere good for the former but if it's skepticism - https://www.reddit.com/r/Buttcoin/ is the only place I know of that is focused on criticism and mocking of crypto currency and the related community.
