Such a great definition and analysis of the current state of social interaction. People don't really have a definition for mainstream adoption because it just "pops up" all of the sudden. My definition of mainstream adoption is when the big companies and social giants start commenting on it, then it has gained mainstream adoption. Attention from the masses from all over the world. Steemit has definitely surpassed that level. We're growing so fast and so strong, I believe we'll pass Reddit and Facebook very soon :)
