A couple of people mentioned that we can't eliminate the friend vote.
I don't actually think there is anything wrong with supporting friends, and often they are friends because of shared interests, I am just trying to think of ways we can make a split between "support" and "vote" if that makes sense?
What I think we need to be careful about is the "I vote for you, you vote for me, regardless of what spam I churn out, the reward is all that matters" because that is a quick way to fill the Hive based sites with poor quality content, driving away any first time visitors (or sincerely active members for that matter)
