What to post..
That's probably the main question most of the users have.. But I seriously think it's one of the most time consuming question to think about.. You'll never get a good answer for that question.
Write about yourself. Express your feelings. Write good stories. Share photos from your last vacation and explain why it's so damn awesome to be swimming with dolphins.. Tell people why you are on steemit. Describe why you'll be here and what people can expect from you. Explain what you expect from steemit or steemit users. Inspiration for content is literally everywhere. In your home, outside the window. Everywhere. Just pick one and get starting! :)
