I suppose people want to collect Steem, and they aren't real bloggers or writers or content producers. The system incentivizes people to mix writing and investing (in crypto, in Steem), and that is not for anybody. Most people have no clue of investment. Many people are terrible writers. Perhaps most of them should simply work a little more in real life and buy a cryptocurrency investment fund (or ETF or investment trust).

Many people write a post and go to chat with friends or family on Messenger or Whatsapp, or Discord. Because the others are there.
