Really enjoying your posts and have upvoted and followed as a result. Seems one of Steemit's fundamental principles may be working after all! That the cream will rise to the top and the market itself will determine value.
I have no problem with the concept or reality of 30 minutes of content by a top contributor or "celebrity" receiving $30K or $300K for that matter. If my name is Adele, I can put out 3 minutes of content and receive millions.
It all comes down to perceived value. Time and a solid mission statement foundation will determine Steemit's true value. Personally, I am quite happy to watch and await developments. Quite happy to speculate on what some of these may be also. But, of course, I then veer into personal and subjective opinion rather than fact.
What are the facts? Steemit is currently over-valued? Maybe.
There is already dissention amongst innovators and early adopters? Yes, this appears to be happening in recent postings, re: 1. Uneven reward system and distribution of "wealth" (Isn't it ever thus?)

1. Uneven distribution of Power and influence re: upvoting and downvoting (see point 1)
2. Celebrities and others gaming the platform for monetary rewards. (Yes, and again, isn't it ever thus? )
   The fundamental problem I see is, despite the somewhat socialist and noble goal of rewarding all contributers for their contributions on a Social Media platform, how do you achieve this in real terms? As long as anybody has even the slightest advantage over anyone else, the Law of compound interest determines that over time this advantage, however slight, will magnify, and this system/platform - Like all before it, will eventually become overwhelmed with "Content Shock" and a small minority will be left gaining and holding all the rewards. Welcome to Capitalism.
   So, my question is, what is Steemit's true purpose? Is it to empower the many or the few? Is it primarily a platform for the distribution of knowledge amongst our species? Or a slight variation on other money-making machines?
   Will be very intersting to watch how this all develops (If it is allowed to "organically" develop that is). Thanks again for your postings. Makes me think, and isn't that what it is really all about?
