What is the difference between a wordpress . com site and a wordpress . org site?
There is actually a mountain of difference between them. WordPress . com is a web builder in a similar vein to Wix and Squarespace. Your site is actually hosted on WordPress servers. WordPress . org sites mean that you download the WordPress software and upload it to your own hosting. Otherwise known as a “Self Hosted Website.”
Like any web builder, WordPress . com is ultimately a commercial site, wanting you to spend money with them. Also like web builders, it is very restrictive in what you can do with it. This article here gives a good insight into the restrictions: https://www.crazyegg.com/blog/reasons-to-use-wordpress/
