A very good post, @markrmorrisjr.
But I believe those are not the only reasons. I believe the system itself can be enhanced. I have just written an article about that:
Too Many Wasted Gems in Steemit!!! Why is that Happening?
Fellow steemians are having different points of views about it. Please check it out and tell me what you think. Since you have noticed the problem, I am sure you can add to the conversation.
Yes, well, it's not called the only five reasons, is it? I'll take a look at your article, but, not everyone can succeed equally, the platform would lose all interest.
Thanks. waiting for your comments
