"Also I don't think it is in the spirit of up-voting content that you genuinely like. " I assume you meant "content you don't like." No one is forced to vote on anything and I agree with you about high quality posts that is already in the plan. But we started 3 days ago so everything is not set yet. As for collective voting we'll have to see but if you read the whitepaper it does seems to be possible as well as collective flagging... Anyway thanks for your input and up vote!
