If there was the same option I used on Reddit to "hide posts you have upvoted/downvoted" so that I can just upvote/downvote each thing I read and it will be hidden after that, it would be great and my main page would always only show new content.

Anyone from the US actually received this? I submitted my request last week and haven't seen the results yet.

I think you meant "from digg to reddit"?
