InfoWorld's long-time columnist Brian Livingston sent out part one of two email columns on how I've turned isbn.nu into a profitable, fun, well-indexed ecommerce site. Don't everyone rush to their servers to follow my lead (it's a niche), but my motto is, "Scraping the Crumbs Off the Table of ECommerce." My alternate motto is, "Rooting Around for Change in the Cushions of ECommerce's Couch".
