It is so true that everyone wants to talk about facebook marketing. Be careful out there, apparently if you learn to get really futzy with the demographic details you can be successful, but I have seen LOTS of examples of the facebook machine eating money and turning it into very few likes (and not the likes that pay like on steemit!)

I hope you take the time to document your journey, marketing is an ever evolving space and I think that people like you are going to be defining the future of the space, not just 'learning' from the text book. This subject isn't like math, there is not just one right answer!

Cheers!
