Yes, minnowbooster is best way for non blogger/investor to earn ROI. Also, I believe there is another one called Utopian. I used MB for a few months and works very well. Just make sure to "unvest" your shares once contract is up b/c it doesn't automatically, you have to manually by delegating 0 at end of term.
