Getting to know the WordPress family
WordPress as a platform and as a community of users has evolved in two main areas. The first one is gathered around WordPress.org—the native, main website of the WordPress project. The other is WordPress.com—a platform providing free blogs for every user who wants one.
Essentially, WordPress.org is about developing the platform itself, about sharing new plugins, discussing the technical aspects of WordPress, and being all "techie" in general. WordPress.com (the image above) is a purely community-driven site where bloggers can meet with each other, and publish their content on free blogs based under the wordpress.com subdomain.
In Chapter 2, Getting Started, we will discuss all of the differences between having your blog on WordPress.com versus downloading the software from WordPress.org and hosting it yourself, but the basic difference is the level of control. If your blog is on WordPress.com, you have less control over plugins, themes, and other details of the blog because everything is managed and made worry-free by the WordPress.com service, which obviously has its pros and cons.
