All of these people could, instead of sharing details of their lives with their friends, instead be spending time on 4chan anonymously grinding out memes. I gather from this post that I am supposed to feel bad about that.
Meanwhile: in a major city in the US, in a market dominated by the likes of McDonalds and Walmart, your odds of successfully starting a small business that depends on a retail channel are significantly worse than 50/50. Most people don't get a shot at starting any kind of business like that, and only a vanishingly small few get multiple bites at that apple. Yet I can use Facebook today to find out about meat specials at my butcher, or someone selling artisanal pickles, or a new theater company, or someone making custom knives as their hobby hoping to try to make a living doing it. And because of the stupid blue "like" button this article rails against, these hopeful businesses can do that without paying for pointless terribly-performing ads in major newspapers or on radio stations, and can have actual conversations with their customers. And again, I gather from this post that I am supposed to feel like this is a bad thing.
So I guess I'm saying: I'm not getting the author's point.
