For example, I can run a 30,000-person mailing list that generates the bulk of my income by spending approximately an hour a week on it. I can create a document that’s both editable and shareable around the world for free with Google Documents or share any file, of any size, using a service like Dropbox. I can replace an entire IT department with one on-contract systems administrator in Berlin who works one to two hours a month for me, and I can learn everything I need to know about the visitors to the websites that run my business with free analytics software.
