Writing has traditionally been considered a solitary craft. You wrote you article or book in seclusion. You submitted it to an editor or publisher and prayed it would be published.
Along comes the Internet and the monsters out of the cage. You now have the ability to self publish your work. You can throw up a Blog, hook up to an RSS feed and syndicate your writing.
You can form online communities with other writers. Readers can give immediate feedback on your work. You can promote your work in the virtual book stores such as Amazon.
The Internet has become a writer's paradise.
With the advent of the Internet, you no longer are limited as a writer,. With a little research you can become a writer/publisher. Think of the possibilities.
Every word you write can travel the globe in the blink of an eye.
Why would you want to be a publisher?
* You can make money before your book is even written.
Before the Internet, writers had to find ways to support themselves while working on their novels or stories. Now if you've got a book that will take any length of time to complete, you can still make money by joining affiliate programs for books by other authors.
* You can start an online newsletter.
What an advantage you have over writers of the past. With your newsletter, your readers get to know you and your work. You have a waiting audience for the day your book is released.
* You can start your own Blog.
