If all you want to do is blog, create a site at wordpress.com, or a myriad of other sites out there. If all the WordPress documentation seems “backward” as you say, you probably do not have the intelligence level to work with WordPress, not that you couldn’t get there by reading and working to understand html, css and PHP.
Bottom line WordPress is an awesome FREE product, with a great user support community for those who want to learn.
Best of luck…..
