Well, I'm not sure what you are trying to accomplish with the buttons other than trying to get people to use the "new post" buttons more.
Here's my take on it though. You make a giant red button for a dog to push for his food, and he learns to use it all the time. Great, but it's just temporary. If you replace it with a smaller button across the room will he still use it?
Obviously people are smarter than animals, but will they break habits after you make changes like that? Or will they go back to what they did before when the obvious buttons are gone?
Just my take on it though.
