I have many pages on facebook and after the fall reach, Me as other people on facebook had a not so good results as before.
However I am earning on facebook. My advice to you is have a specific niche that also the reach is lower you shouldn't have any problem because the fans could search your page always.
For example.. For me, is much better have a page about soccer of 500.000 fan that a funny page of 2.3 mln fans.
Then, consider that with 2.3M of fans maybe he has merged any pages or clones.
This is my experience and advice on facebook.
