Atm the 'NEW' section is not very busy, content creation has dropped alot so it is easier for good content to be seen and upvoted by the few people we have active with any decent stake, if/when Steem becomes busy again alot of authors are going to fall through the cracks, post promotion helps them get visibility above the rest. Another idea is burning SBD or Steem to get a featured slot on Steemit.com or some trending page ranking.
