Douglas MacMillan: I’ve collected 101 of the very best freebies—including enough free software to run your own business or become a YouTube video mogul—all without putting my hand in my pocket. Of course, I did have to give something, even if it wasn’t money. In some cases, I had to click on an ad or watch a video. In others, information about me—such as how I spend my time online, or how I spend my money—was so valuable it entitled me to free products.
