Only the dynamic pages like Archives, Categories and Tags created by the software when we publish a post will update automatically update with new posts.
By default the front page of the blog is the Page that displays all posts in your blog. You can create a static front page and have your published posts display on another page http://en.support.wordpress.com/pages/front-page/ but doing that does not change what follows.
Though there is only one dynamic page in a blog for posts (not pages)http://en.support.wordpress.com/post-vs-page/ and we cannot post to more than that one page, we can create the appearance that we have posted to more than one page.
This guide will walk you through how to create category pages for your blog, to display groupings of similar posts on pages other than your front page.http://en.support.wordpress.com/category-pages/
