On 2017 when I arrived here there were much more comments than posts and posts were shorter. There was a time that people even asked for a nesting in comments -the way they were shown-. Luckily people began to create better quality posts and somehow people also began to comment less.
People keeps comparing Steem with Facebook, while that's wrong. Facebook is about people you expect to share some more intimate moments in your life. Steem is for writing about something and getting rewarded for it. People can also comment, and be rewarded for their comments. Steem is more like Medium or a Twitter without character limits.
