After reading up on other's experience, I ran an experiment last week:
I started a stupid comic blog (http://omgcmon.com). I made a facebook "page" for it too.
I posted an link from my stupid comic blog to the facebook "page". I posted the same link to my personal status.
The posting didn't even show up in my OWN news feed, unless I changed it from "top stories" to "most recent". (All other posts from me, show up in my "top stories" at least.) My friends & family didn't see it either.
But, when I took the same image in the blog post, & put it in facebook as a "Photo", then people saw it, commented, liked, etc.
So, it sure does look like Facebook knows that the link was on a "page", & then used it's secret algorithm to suppress it, as it knows that will, over a large population, cause more ad dollars to be spent to boost "pages".
So, the money/profit will flow well, but not forever.
Run your own experiments if you doubt it. It's not hard to get this data yourself.
