Yes, it's a little ambiguous if you're just a blogger with no familiarity with cryptocurrencies.

This would be how I see it (and I could still be wrong, after six weeks of reading!):

"Steemit is a social blogging and content platform where members can share writing, art, photography, music, news and more. It is both an independent application, as well as a framework supporting other applications (Busy, Golos, PeerHub, etc.). Steem is a virtual currency like Bitcoin, which not only serves as the basis for rewards to Steemit users for their contributions, but can also be used as payment at a growing number of web sites and physical locations around the world."
