From the site:
Booksie is a free social publishing site that provides a place where writers and readers can connect from across the globe. Over the past several years, tens of thousands of writers have posted hundreds of thousands of short stories, novel, poems, articles and more.
Booksie was created specifically for creative writing and literature. Organizing a book on a blog is not easy. Blogs also don’t organize your portfolio. They are designed for time-based journal writing, not literary writing. Check out the profile of some of our users and you’ll see how Booksie organizes your portfolio and gives you tools (including a micro-blogger) to connect with your audience. You can Feature certain work in your porfolio, embed images and video, tell your writers about the latest news (micro-Blogging), and keep tabs of your fans.
