When I created this blog, the intent was to have a space to express ideas about wealth. So far, the blog has been a great resource. I not only get to publish current ideas flowing through my head, I get to look back at previous posts to see what my mind set was on a certain topic. Also, with the help of Google Adsense, I have been able to make money doing it.
Google Adsense allows you to manage what ads end up on your site. It has an excellent account section that gives all the analytical tools you might need. If you are starting a blog, and qualify for the service, I would highly recommend using Google Adsense if possible.
