A proactive step to generate revenue which is always a postive. I think they should really look at not just network ads but selling that space to direct brands which is how you really make money on ads, I've seen this from personal experience
I really think a big opportunity is the promote section of the site it could be revamped to be more intuitive and auction based so it keeps changing based on impressions and users can bid for top spot based on CPM or CPC using SBD/STEEM. While it may serve to recycle steem and SBD back to steemit it may also result in other cryptos being sold to buy steem just for better promo opportunities on the site
