My experience is this.
Have built up fans for my clubnight Discotekken over the last 2 yrs or so on facebook. At about 1300 now which isn't anything crazy but I'm happy enough with it.
Before, when I posted, everyone who had (voluntarily) liked my page, would see my post, if they were online, or perhaps next time they were.
Now, out of 1300, facebook restricts these views to 200 or so. This number goes up depending on how many interactions the post gets ie likes, comments etc.
I have the option to pay 4 pounds sterling to enable all of my fans to view my post, this is PER POST.
Afaic they make fucking billions on advertising already, so this move is simply greedy & stupid, as I can't see people willing to pay that kind of money to simply display a single post.
Lastly, in my scenario, and most other small clubnight promoters, it's not like we're hugely profitable businesses, so again, a stupid move from facebook & all it's going to do is decrease my interest in using it to promote ma biz.
*edit, may as well get a plug in
