NB: We use WordPress (WordPress.org), not the blog host WordPress.com WordPress.com provides free blog hosting for registered users. It is owned by Automattic and run on a modified version of WordPress. A free WordPress.com site includes a WordPress.com subdomain. For instance, example.wordpress.com The point of this article is WordPress.com acquired wp.com in 2009 from Yahoo. So, WordPress.com could let users have wp.com subdomain. For instance, example.wp.com. It makes the url shorter, beautiful and convenient.
