If you are a newcomer, you'd be ranked a "Prospect". If you are new at blogging and would like to get more of a readership, you'd be considered a "Rookie". If you've become established and blog consistently, your ranking would move to "The Pros."
When BYB started, there was no such thing as a Hub. Now there is. The reason? There's a ton of talent out there and not enough exposure is given. We're giving you that opportunity at BYB. Good luck.
