I've certainly had ideas at the past and no doubt in the future for things to propose, but the real idea behind the SPS is to have an open system where many people can suggest ideas and provide a mechanism for stakeholders to vote on those ideas, so it's not so much about my own ideas.

Making sure that we choose wisely what to upvote is of course a key ingredient for the success of the SPS as a work allocation system. I don't know of any way to guarantee such a thing (if I did, I suppose I would be the wealthiest guy on the planet). But I think it is critical that we have such a system to increase the rate at which we grow the Steem ecosystem. From my point of view, progress has been much too slow in the past and we need to expand the available pool of people that can help out. No doubt there will be proposals that fail or don't provide benefit, and voters will just have to learn to make wiser decisions in such cases.
