If you are a fan of the current incentive structure, and are mainly interested in long term investment of Steem through buying SP, then you should like this proposal. This proposal is intended to convert Steem's web traffic into money, then distribute that money proportionately among SP stakeholders. If you are a SP stakehoder and like free money, then you should like this proposal. I think they key is making the advertisements unobtrusive while still making it a lucrative endeavor for SP stakeholders.
