Peter Suber: The largest obstacles to open access are unfamiliarity and misunderstanding of open access itself

"I’ve already complained about the slowness of progress. So I can’t pretend to be patient. Nevertheless, we need patience to avoid mistaking slow progress for lack of progress, and I’m sorry to see some friends and allies make this mistake. We need impatience to accelerate progress, and patience to put slow progress in perspective. The rate of OA growth is fast relative to the obstacles, and slow relative to the opportunities."
