WordPress, offered by most blog hosting companies, is great for blogs and remains the easiest system to setup, use, and run your blog on. The great thing about the WordPress community is that people are more than willing to share their hard work with free themes. Because there are so many free themes out there, however, finding the right WordPress theme for your site will take time. You will have to go through many themes before finding the perfect one, but you also need to worry about more than just looks. Many themes contain embedded links to affiliate and promotion sites which can be harmful for your site.
