I think one big thing is that early submissions get upvoted disproportionately, not because they’re necessarily good, but because they’re not necessarily bad. People might realize they like later submissions more, but the damage is already done. I think we should have voting disabled until a certain day, maybe Friday, upon which submissions would be closed off and people could vote. Either that, or people should be allowed to change their votes (though I can see potential for abuse there).
