Yeah, but each sub to a greater or lesser degree, has its own hivemind you'll be run out of town (or possibly even banned) for challenging. And the average member of Reddit is quite willing to spout off confidently incorrect BS and downvote people into the ground who actually know what they're talking about.

Not exactly always a reliable source of info outside uncontroversial niche topics or places like /r/AskHistorians that actually moderate. And even there I've seen the occasional humdinger.
