The catch with Steemit is that you get paid directly by the users of the platform, who enjoy your posts and give you votes. You can make money from the first creation of content.

Exactly! That's it. That's boon and bane at the same time from a marketing point of view. Because on one hand this chance attracts a lot of new interested users, but on the other hand it encourages expectations that can't be fulfilled.

If people are arriving for some hit and run posts, let them come. They will run the hard way that Steemit is not a get rich quick scheme.

I don't agree on that one. Imagine that steemit was a coffee shop and everybody out there was telling that you could get the very best coffee in the world there. Imagine that steemit was YOUR coffee shop and that you were the only person that knew its secret: to get one of these coffees the customers need to sing a song. I bet that a lot of potential customers that enter the shop would say: "Singing? Me? In public? Are you kidding? No thanks." But if you told them before, maybe they would have prepared themselves and brought a song... just to get one of these delicious coffees everybody's talking about.

You don't win having them in your shop once. Only a loyal customer (user) is a valuable customer.
The very same thing happens on steemit. 100,000 dead accounts are worth nothing.

Sorry for the long side kick :-)
