The content silos handle creation and hosting well, but they're generally mediocre at promotion unless you're already hot (though this did not used to be the case). The only nut that needs to be cracked to pull off content creators is no-strings creation/hosting along with decent visibility in SERPs.

Promotion is up to you no matter where you place your work.

You end up promoting a page where the competitor is 1 click away. You are investing in facebook first, your own business second. That people click follow doesn't mean you just get to send out messages. That you have a lot of likes doesn't mean people clicked the like button. Then there is the privacy of your audience. They might not care about it, you should set higher standards.

An optimist would look at that and think how great it is that they are one click away from their competitors.

FB is making billions for a reason, there has to be something that works there. I'm an optimist too, I believe its just that people are still naive enough to use FB. I hope it implodes sooner rather than later so that things can go back to normal. :-)
