On the Internet, it is very possible to make money without selling any product. One way of doing so is through starting your own ezine, also known as an electronic newsletter. As an ezine publisher, not only can you easily achieve the benefits a conventional newsletter publisher enjoys without having to chop down several trees in the process, you can easily and conveniently spread your marketing influence and expertise to your base of subscribers from the shoes of an ordinary individual. This is a nice ebook that informed me alo about this subject - pdf format and 25 pages in length.
