A curator is someone who curates the content written by others on Steemit by “resteeming” them to their own blog. As a result, curators earn a portion of the revenue generated by each piece of content they curate.
Authors write their own content and publish it to their Steemit blog.
Steemit users can do one, the other, or both as a means to generate STEEM.
Thanks for this addition... Curator is also upvoting others posts, not just resteeming...
