Even if they aren't photographers, you know how to shoot a great photo. You ask them what could be the possible theme of it. And, who knows, their suggestion could just be the push you needed. I think all these little things are justified in their own right honestly. No discussing submitted items publicly means "Think before you act". Vote from Flax' shortlist instead of global vote from all the items means "These are all items we'd pick if there weren't better ones, so feel free to pick something you'd want to see the most!" Seriously, no need to make it an anarchistic contest. It's in a good place right now. Chill man.
