Pandamian is a new free service which makes it extremely easy to write, review and discuss, and publish a book online.
The service allows anyone who has registered for the service, to get feedback, discuss and review with others his writing work in progress, and to build a "community" around a book.
Pandamian fully and freely supports text conversion to EPUB, mobi, or PDF file formats.
The guys behind Pandamian (mostly from Singapore) are doing this because they believe "writers are the new publishers" and because they want to position themselves as the "Tumblr for book writers".
