Wordpress.com vs Wordpress.org

Wordpress.org is controlled by the user and Wordpress.com is controlled by Wordpress. Wordpress.com is free to use and Wordpress.org is not. Wordpress.com allows for limited customization, while Wordpress.org allows for full customization. Personally I would use Wordpress.org because its more customizable and I would be the true owner of the web page and wouldn't be owned by Wordpress. If I had a business I would want to use Wordpress.org because using Wordpress.com would mean that your domain wouldn't look very professional.
Wordpress.com is more for people who don't want to have to stress over themes and things of that nature, while Wordpress.org is more for the people who want to do all the coding and custom design. If you are interested in making a website check out both Wordpress.com and Wordpress.org.
