What’s the Difference with WordPress.Com & .Org ?
The software is almost the same but...
WordPress.Com sites are hosted for you by the creators of WordPress (Automattic). You can create your own blog within minutes. Your selection of themes and features are limited.
WordPress.org is the information portal site for self hosted WordPress websites. Click here for a list of recommended web hosting providers. With a self hosted WordPress site you can install any theme or plugin for extra features but you're responsible for the upkeep of your WordPress installation (with some help from your web hosting provider).
I also run a website primarily for WordPress self hosted sites called: WPVerse.com.
