Evolving online business, from books to writing

Today I stopped by an online book selling business blog (the blog was about the business which was at another site) that I sort of enjoyed, and discovered the owner had discontinued that effort, but is now writing for other online businesses. She'd become successful enough at finding and selling books, that she had begun to outsource, which cut into her profits and her fun. Story here. Now she's created a new site for her new business as a copywriter.
