Blogging is something that many people are taking up and surely they can count on WordPress for good exposure. It is not really hard to understand. There will be new commands but if you walk through it, you will find the site software quite easy to understand and navigate in.
Besides, you have the visual editor to help you out. It is the simpler way of blogging and formatting as you want to see it. If you feel that you can master it, then you can always switch to the HTML editor where advanced features and commands can be used.
