This is my .com, meaning NOT self hosted. This is a blog host. This service is limited in terms of template and performance. It does not let you add pluggins, although many of wp.com widgets provide pluggin functions. A widget allows you to arrange sidebar information without writing code. wp.com offers more than 60 themes. If you want to customize your theme by editing the CSS you must pay an annual fee. This option also also occasionally ads advertising to your blog unless you pay a no-ad fee. You will also pay for hosting videos with this option. This option provides a support section plus forums and a support contact form.
