Just in case you are new to blogging or are just considering starting your own blog, or you have a blog and are just now considering monetizing your blog, I think a short introduction to what a blog is will be appropriate.
As the internet developed to become what it is today, many webmasters discovered that netizens wanted to know which websites had recently been updated and which had new information on them. Web surfers were searching new and exciting information and did not want to have to go check sites themselves to see if they had been updated recently. They wanted someplace they could go and see just what was new.
There were some pretty sharp programmers started posting logs on their own websites which told their site visitors which websites had recent updates or new information on them.
These weblogs, as they were called at that time, were like an informal directory of "what's new" online. These weblogs, and the technology which powered them, eventually grew and changed to become the blogs of today.
