What does earning potential have to do with stars?
Anyway, I'm not missing any point. The rating system on Helium is a joke and if Helium want the content ranked quickly and properly then this is the wrong way to go about it. Ratings pairs is a good idea, but you should be to select individual categories, not any old muck within channels. If there's one thing the negative Helium people seem to agree on, it's the rating system sucks ass.
In fact, I believe the rating ranking system was set up to, like Ciao, fool the people into doing something that's clunky, just like when the dot system was brought in to disguise the drop in payments. It's making folk think they have to rate when, in reality, they don't have to do any such thing. It doesn't serve any useful purpose to the members.
