My two cents
:
I think the most important part of all is to create high quality stories. If the few people that start reading your stories like it, they will pass along the word and the stone gets rolling. Therefore, I think that a good way to start promoting your writings is by 'befriending' influencial bloggers. A.k.a. you ask them to read your story and write an honest review about it.
Also, I think it's important that people have the chance to get to know the author. This means you have to get yourself out on the internet! Make sure that when people read about you, they will also get triggered to read your story. You don't have to make a fancy website, a Wordpress template will do as well. Just make sure it looks nice & professional, e.g. for wordpress blogs I would buy a package that includes your own domain and has some webspace (like, for example, this one:
http://www.1and1.co.uk/wordpress-blogs ). Also, make sure you use a nice template design and ofcourse, that the information on your website is well written.
