You are correct. One that first turned me off to Steemit was that there was no proper explanation of how it worked on the site and no explanation of what the 3 coins were. These were all things that took time to find and understand and I have an easier time understanding it because I am familiar with cryptocurrency. The mere fact that people can get paid anything attract all sorts of people here and the ones who earn will be "forced" to learn how to get their money. A crash course in Cryptos if you will. The dollar signs next to number on popular posts will attract mainstream attention it is a great marketing tool. Your points are all good though.
