You should understand the distinction between Steemit vs. Steem -- a common misconception.
Steem (or SBD) is a database and has the same name as the underlying token used in the blockchain which rewards you for your content based on how other users vote on your posts.
Steemit is just one interface that displays the content that is stored on the blockchain.
Thank you for this clarification, @complexring! I think I've got it now. :) I'm going to edit my post and its title accordingly.
