Earlier this year comedian Louis CK raised some eyebrows when he sold downloads of a live show through his website and pulled in more than $1 million in about a week, despite the fact that fans could easily download the content for free. Now, he has done it again: instead of a traditional tour, he decided to sell tickets through his website, and sold $4.5-million worth in under 48 hours. Content creators of all kinds — authors, musicians and others — would do well to learn from his example, and that of others like Amanda Palmer, who recently financed a new album and tour through Kickstarter. The main lesson? Building a community is more important than ever.
