You are very eloquent, and you mirror my thoughts exactly. The thing is, I have a proposition for increasing the site engagement as well as educating them about it. It is about sending whatever rewards happen to be as steem power fully or in part.
You aggregate new and undervalued posts, and send SD to the authors? Send part as SP instead, and advertise that you are doing so and why!
You are running a contest? Give out part of the winnings as STEEM POWER! Explain why you are doing so, and have fun!
You are offering some kind of service? Ask for part of payment as STEEM POWER!

Anyhow, I am using the tag #spreadthepower with that in mind, and my post explaining the idea can be found on it. So far not much exposure for the idea, but I do hope it gains some traction. Since it works on both educating people, as well as increasing their vested interest and vote weight.
So if someone interested in participating, they can write a post with that tag describing their service, or contest, or whatever else.
