Looks like the competitors of Steem are pushing forward their ad campaign. 
I am the "drays" user mentioned in the Pinterest post you refer to. I know a lot on how Steem was launched, as I was there from the beginning. Yes, it was not easy to figure out how to mine this. Yes, indeed, an effort was needed to mine it, and a lot of time needed to understand what this is all about. Truly saying, I invested not enough of my time, and so mined a bit less than I could). But I don't try to blame the developers for that. You cannot make money out of nothing, you should invest your knowledge and your time, and this is exactly what Steem developers ("thereverseflash") requested. The source code was open - so someone with enough skills and time could read it and understand. The ones who did not have the skills and/or time, were not rewarded. Isn't that ok? You always get paid according to the time and skills, at any job, so I think its ok for Steemit developers to do the same.
To summarize this: while being hit myself by the absence of information during initial launch, I do not complain, and I completely understand the Steem founders. They mined the lion's share of Steem, but it is only fair - as they are the ones who invested a lot of time, talent and work into this project. At the same time, they really gave the chance to others - a chance to get something according to the time and skills they invested at the time.
