It seems Facebok is adopting fast. In a post I wrote more than a year ago I noticed some issues in the voting system on Steemit. The issues still stay the same. "The current concept of content evaluation at Steemit by voting has several flaws. The first and the most obvious is that you can vote for a content (at the feed) without opening the post. Who on Earth can tell if a post is worth it without reading it first? Another one is that you can vote for your own post and yes, people do that. The most controversial issue is that users with higher STEEM power (whales) cast the most valuable votes. "So let’s gather 50 people buy STEEM power and vote for each other posts and win some cash.""
