One thousand is a feasible number. You could count to 1,000. If you added one fan a day, it would take only three years. True Fanship is doable. Pleasing a True Fan is pleasurable, and invigorating. It rewards the artist to remain true, to focus on the unique aspects of their work, the qualities that True Fans appreciate.
The key challenge is that you have to maintain direct contact with your 1,000 True Fans. They are giving you their support directly. Maybe they come to your house concerts, or they are buying your DVDs from your website, or they order your prints from Pictopia. As much as possible you retain the full amount of their support. You also benefit from the direct feedback and love.
The technologies of connection and small-time manufacturing make this circle possible. Blogs and RSS feeds trickle out news, and upcoming appearances or new works. Web sites host galleries of your past work, archives of biographical information, and catalogs of paraphernalia. Diskmakers, Blurb, rapid prototyping shops, Myspace, Facebook, and the entire digital domain all conspire to make duplication and dissemination in small quantities fast, cheap and easy. You don't need a million fans to justify producing something new. A mere one thousand is sufficient.
This small circle of diehard fans, which can provide you with a living, is surrounded by concentric circles of Lesser Fans. These folks will not purchase everything you do, and may not seek out direct contact, but they will buy much of what you produce. The processes you develop to feed your True Fans will also nurture Lesser Fans. As you acquire new True Fans, you can also add many more Lesser Fans. If you keep going, you may indeed end up with millions of fans and reach a hit. I don't know of any creator who is not interested in having a million fans.
But the point of this strategy is to say that you don't need a hit to survive. You don't need to aim for the short head of best-sellerdom to escape the long tail. There is a place in the middle, that is not very far away from the tail, where you can at least make a living. That mid-way haven is called 1,000 True Fans. It is an alternate destination for an artist to aim for.
