WordPress.com vs. WordPress.org
WordPress.com is a hosting platform that makes it easy for anyone to publish online. You don’t have to download software, pay for hosting, or manage a web server. WordPress.com has hundreds of themes, and includes the functionality of many plugins, but you can’t upload your own plugins or themes.
WordPress.org offers free software that you can install on a web server. You can upload and install themes and plugins, run ads, and edit the database.

I just wanted to send a note to all the WordPress staff to say THANK YOU! I am a total newbie at blogging, but WordPress is so easy to use that it's made things a breeze for me to start up my blog and to keep at it. You folks all ROCK!! Thank you so much for your work on WordPress! Happy Monday! Oh also, the customizable features are AWESOME!— Dodie G
