Welcome to Steemit!
If you want to build community and find supportive people who will help you grow your following check out the #MinnowSupportProject. @minnowsupport works to help people find their way around this platform through their website and radio station.
Another group which is very helpful is the @welcomewagon. They create content which can help you learn about different aspects of this site.
I use Stack editor to write my posts, it's useful to see the posts side by side and helps me to learn the markdown system.
I am glad you found your way here, and again welcome!
