Web Publishing Tools for Kids?

fuzbuh asks: "I want to help an 11 year old who wants to publish a site for kids, and am thinking about what tool(s) to provide for her. Her experience is limited to email, web browsing (on kid sites), and computer games. This, as a first step for her, needs to be easy, and more focused on content than form. What do people suggest for tools for her? A web based page builder (which one)? A WYSIWYG editor (may be a bit complex). A 'Wiki' where only she can edit? Maybe I should just start her with a blog to post her ideas and stories. What have others done? Any ideas and/or suggestions? Thanks in advance!"
