Wow, I did not know about this, so thanks for sharing!
I think it's great how something like this which requires a high level of trust can be placed on a transparent blockchain system like ours. And there are so many more applications of a similar type- education reviews, medical services, even banks- that could create similar apps.
Also bodes really well for those who have investments in the Steem token!
I do like that aspect of the blockchain being transparent! thanks for taking the time to check it out.
