Day late and a dollar short.
The business pages in their current form have driven many from facebook already. The biggest reason I've heard so far is that people are getting tired of all of the constant nagging. Sure, they'll buy a boost, but facebook insists on nagging them again about boosting the same thing they just boosted 5 minutes ago.
The first exodus came when facebook combined all of the non-post content at the top of the page above the posts. Took facebook almost a year to figure out how much of a total blunder that was. Users would go to a business page and see the same pictures that were posted 6 months ago, and would never scroll down to see the latest posts ... engagement fell off a cliff.
The fact that facebook has been rewriting so much so often over the past 6 months is pretty indicative of facebook's desperation. Never-mind the Junior developers with their big box of colour crayons that only get paid $15 an hour, there's also the bad press facebook has been getting of late.
Back in the day when facebook let you code right on the site ... produce your own pages per se', business was good. People that couldn't afford a stand alone site would pay decently enough to have us go in and code on facebook's existing platform for them. Those days are gone.
I go into facebook now and I'm reminded of the days before myspace took the dive. A lot of unnecessary clutter all in the hopes of keeping the few thousand remaining users on board.
Quicker links, more topics, concentrated ... should improve stickyness and returns.
I think we just somehow already know that this isn't going to work. If the internet has taught us anything at all over the years, it's that once a user leaves a platform, it's very unlikely that they'll ever return.
