The only issue being that there are a number of small, focused subs that contain the best information and discussion on certain topics on the interwebs. I don't give a fuck about the site itself, but the people active in say r/machinelearning and a number of other subs are incredibly valuable to me.
There would have to be a mass exodus of entire subs for this to change. Which probably won't happen until the situation becomes untenable. I don't believe reddit's leadership, despite the harebrained ideas they have shown so far, would Digg themselves into such a hole.
