That's good news. Ads could provide a great potential revenue stream for Steemit Inc as well as content creators. For ads to be more successful, Steem and/or Steemit will need to be changed in a few other ways as well. View counters will need to be returned for posts. Curation rewards will need to be improved, I recommend about 75% for curators and 25% to content creators. The problems with the SBD peg to USD needs to be fixed, this seems a little indirect but it would make a quite a difference in the long-run.
