I mention this, because to get most of the neat-o features, you need the full version that you install yourself. Or, your webhost might have a "one-click-install" for a WordPress blog. It's the same thing as the full version. But, your webhost will install it. Your webhost should provide you with an interface to activate the blog option.
If you goto WordPress and sign-up for a "myBlog.wordpress.com" account, you can only install the official plugins. For example, you can't install 3rd party themes and plugins that your friend made. On the plus side, if you're not technical, you don't have to upgrade your blog when new versions come out. Wordpress will handle that for you.
