if i'm right then could you add more of the voting power to the people that contribute more to Steemit? for example the bots probably don't post any content , they probably just come on and just upvote post, But the members who are posting content and adding more value to the site could have more weight added to there voting power.

This is already going to happen over time. Content rewards redistribute ownership of Steem Power to both posters and voters. Someone who both posts (includes comments) and votes well will make more than someone who just votes well and doesn't post.

Much of the current reaction is based on the early adopter dynamics and not necessarily what will happen once Steem Power starts getting redistributed. Even right after July 4, things will change a lot, as there will be a much larger group of people with big chunks of Steem Power than there is now.
