Totally agree. It's a huge challenge for brands that are selling products that aren't highly differentiated too - I had the benefit of selling a niche product that's partially built on scarcity.
Commercial products are tougher, but they also have agencies whose job it is to spend time and money figuring out how to reach people. As I said, I spent about 30 minutes creating these ads.
A big part of what I like about Facebook is that it enables me, as a business owner, to compete on an equal playing field with massive Fortune 500 companies, and in this case benefit even more from Facebook Ads than they do. That's huge for anyone doing anything disruptive, whether it's a startup, a local business, or anyone competing with the status quo.
