What is WordPress?
Fact is, the WordPress community is huge. The software powers nearly 38% of all websites online (there are billions). That's a huge amount, so there are bound to be questions, comments, and inquiries about how to use the system.
For the longest time, most people didn't know there were two versions of WordPress. If you aren't in the "know," then it can be very confusing. Most bloggers will suggest starting out on WordPress, but don't make the distinction between which one you should go with.
Fact is, WordPress is the world’s most popular content management system. It was released in 2003 as installable blog software. Initially, the platform was very simple and was used by people to post their thoughts online in a blog format. Over the years, WordPress grew in terms of functionality and is now capable of running very powerful and complex websites.
