Very good post. I think we forget that steemit is a very new site. It's grown quite a bit in that time. But there are no guarantees. We don't know what the final version will look like. If your post is lucky to be upvoted by people with a lot of SP, you can make a nice amount of money. But that may happen every 1 out of 20 posts. I have nonfiction kindle and Createspace books, websites with ad revenues and other ways to make money. If my posts start to consistently make money, I'll keep posting here. But if they don't, I'll put my energy into other money makers like Fiction :)
