It is a great idea and great concept but this concept is not new to the internet , which makes it difficult for people to believe in such social media sites. Many sites with profit-sharing concept have come and gone. Yea YouTube is an exception. Aside from YouTube, the social media platforms that still survive are the one like Facebook and twitter which give no direct monetary benefits to its content creators. So I still don't know how much i should trust Steemit... let's wait and see with a great hope that Steemit makes it to the mainstream and revolutionize the social media system as whole.
