Remember: be sure to check out the “New,” “Rising,” and “Controversial” sections regularly. Only reading the default severely limits the information you receive – what’s in the other sections can be very surprising.
Many interesting posts and topics are not voted on or are downvoted for a variety of different reasons. Some good, some bad.
Nevertheless, by going to the other sections, rather than merely "Hot" or "Top," you'll find a considerable more amount of information, opinion, and perspective for your decision making and understanding.
Additionally, you will be able to contribute to the democratization and decentralization of the subreddit in a more robust fashion.
Don't… default… on your education!
