WordPress has become the most widely used CMS ever. But many newbie bloggers get confused when choosing between the two flavors of wordpress – WordPress.org vs WordPress.com.
In short WordPress.com is the free alternative just like blogspot.com. You donot have to bother about hosting and maintenance. on the other hand wordpress.org is the self hosted version of wordpress giving you ultimate control over the features of your website/blog.
We would definitely recommend wordpress.org as it will give you the power control almost every aspect of the blog but then again with great powers comes great responsibility of managing the site on your own.
