Hello, @stevecronin, and Welcome to Steemit.

Below are a few basic points of advice re posting on Steemit.
1 – Longer posts are more lucrative than short posts. If you make a post of 20–30 paragraphs, it's more likely to earn rewards.
2 – Include some photos, images or graphs, to complement the text.
3 – Make sure the text and photos are formatted properly, so that your post looks attractive and appealing.
4 – Be yourself.
5 – Be interesting and informative.
6 – Create quality content. Steemit is intended to be a platform of quality content. (You will see many insignificant posts with meager content and no quality. Most of those of posts [called “shitposts” by Steemit whale Stellabelle] will earn few rewards and soon pass into oblivion.)
7 – Get online and start curating. Read various posts, comment on those posts you find interesting, and upvote those posts. That’s the best way to attract followers.
