Most bloggers set up a blog to make money in the Internet. I admit this was my primary reason why I decided to build my blog. I wanted to earn extra money for my personal expenses, especially to help the studies of my siblings in terms of financial aspects. If your goal is similar to mine, then I recommend joining Bloggerwave. It was recommended by a blogger friend to me just recently. Since he was satisfied with the program, I joined to experience it myself.
Joining is absolutely free and you can join as long as you have a blog regardless if it is a free or self hosted. Payments are sent thru Paypal with no minimum payout. For more information, click Bloggerwave.
