Every social media has spam, bots, fake accounts and bad posts, Facebook, Twitter, Youtube, you name it. The currency here is the people, no one is asking you to invest money on it. You get paid 0 dollars everytime you browse Facebook and you look at ads and baby photos all day!
I'm not saying Steemit is the ultimate platform, it has a long way to go, but it has definitely gained traction and opened a Pandora's Box if you will. Companies could buy Steem Power and influence markets, create their own ad channels, hire great curators, the possibilities are endless, the truth is most of us don't really know where it will be in 6 or 12 months.
