Wordpress blogging script is very easy to learn and install.
When you sign up for a web hosting plan at a web hosting company the web hosting company will most likely have an auto installer where you can click a few buttons and just enter a little info and the wordpress blog script will be installed for you in just about a minute.
Once it's installed it's also very easy to install new themes and plugins by just searching on the admin side of your wordpress blog.
Then you just click a few buttons and the plugins and themes are installed for you.
