It is very confusing for people to tell the difference between wordpress.org and .com, and I am going to try and help clear up some of the confusion. Wordpress.com is a tool that people can use to make a website that is easy to make and one that you don't have to host yourself. Wordpress.org is a program you download and make a site that you host yourself. With Wordpress.com you have to pay if you want to remove ads, and with .org your site won't have ads unless you add them yourself. With the .com version you are limited by the storage that Wordpress gives you. With the .org version you are able to add as much storage as you want. Those are the main things that are different between .com and .org. Wordpress.com Wordpress.org More Info
