Since I don't post long-form content often, if at all, one thing I do to help promote Steemit and it's users is curate the best content I find on Steemit onto my Scoop.it pages that have over 90,000 followers. Then I share most of these links with my social media profiles for another 100,000 people. I provide links back to the article, the author's profile, and a blurb about joining Steemit under every post.

Here is the most recent post as an example:

These posts are also listed in the main directory of Scoop.it for added exposure and linkjuice.
