RE: My first post, my first book.
I'm sure this community will be here to read every word. Best wishes. I love a good sci-fi novel. :)
For best results on here, write a more detailed introductory post about yourself. Tell us about who you are, what you enjoy doing, and your goals for using the platform, including your novel plan. Be sure to tag it with #introduceyourself and #introducemyself plus 3 other tags that are relevant. That will help get you some visibility.
Next, go find other people on here who enjoy the things you enjoy. Search via tags to find other authors, other sci-fi fans, etc. Give upvotes and thoughtful comments, and pretty soon you'll have more followers to read your content!
Also, if you haven't already, go read the Steemit FAQs. They will help answer many questions you may have about the platform.
Good luck!
