Welcome to Steemit, @conradnjb !
Yes, its all a bit complicated at first, but you'll get into it I'm sure.
Best start with reading the FAQs and other info on Steemit.
About what to post... Don't ask what people want to see - post what you know about best. You wont get rich here anytime soon, either way.
So post about things that interest you, and same as important: talk to people in comments and replies, to make serious followers. Avoid follow beggars.

So, have fun and success with this new way of social media called Steemit!
