I gave up reading comments there quite some time ago. As I said, reddit doesn't collectively get things (like blockchain) wrong--individuals get things right or wrong, and reddit most often promotes the wrong answers because wrong answers are more spectacular, more exciting, and quicker to type than the truth.

Reddit's chronological weighting is a very big factor in this. If your comment comes a few minutes after a post, such as the time it takes to read the content of the post--or if it takes time to thoughtfully type out a response--it is scored vastly lower by the black box and is less likely to be seen and voted on.

There are certainly exceptions, but unless you already know a lot about the subject at hand it's very hard to pick them out among the deluge of jokes, smark, and people rapidly parroting the misconceptions of others.
