What could be a nice feature is to have another post page, that could be another than the main one and the ability to set as home page .
(1) There is only one page we can post to in any blog and
(2) The static pages http://en.support.wordpress.com/pages/ we create do not automatically update.
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 post that displays all posts in your blog. 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.
We organize posts by assigning categories to them. You can create a custom menu and add the dynamic categories pages into the custom menu.
We can also add other items into a custom menu like static Pages http://en.support.wordpress.com/menus/#adding-pages but as I said above no static Pages will ever automatically update.
There are many common errors, misunderstandings and misconceptions when creating custom menus and there are some tweaks you can use to improve your custom menu as well.
re: static front page
When you want to have a static front page then you need to create two pages. The first one will be the front page and the second one is for published posts to display on. http://en.support.wordpress.com/pages/
After you do that you go to > Settings > Reading and make the designation change and click “save changes”.
