A Simple Pic of Why I don't Like Facebook> Oops! Google Chrome could not find www.facebook.com
Facebook hides itself from search engines like Google. So if you build a platform on FaceBook to communicate to your audience, you are not visible to many potential viewers.
It's a better idea to put your core content on a site that you have control over.
WordPress is an fantastic website building product that happens to be free. Add a premium theme and you are off to a solid start that you have control over.
By the way, Facebook, Twitter, Google+ all have their merits and you should use them to share and learn. Just don't let your main offerings live there.
