I don't understand why if i moderate on a story if i post i lose the moderation. As long as i can't moderate myself this should be fine.
Put more moderation categories, such as -1 wrong
Want sponsored stories? Just label them like android police does.
Simple text ads or non animated images are fine. NO FLASH.
Minimalist design for mobile users.
Maybe auto remove a story if the users label it as dupe. Also, for editors, auto search before approving stories to the front page to avoid dupes (like some bug trackers do before allowing you to create a new bug)
