RobbiesBlog.com runs on WordPress.org and it is a great FREE to use platform however WordPress also offers WordPress.com where you can still use the service for Free but it has some limitation to it, you can’t use your own domain name but instead operate a sub domain i.e RobbiesBlog.WordPress.com and you can’t have any advertising on your blog either so making revenue from a WordPress.com FREE Version is harder than WordPress.org but also there are some benefits to WordPress.com sites such as maintenance you never need to worry about updating to the latest version of WordPress as WordPress.com does this automatically.
You can purchase a Premium or Business Wordpress.com site these are Paid options that offer more custom features and you can see them below.
Do you use WordPress.com or WordPress.org?
