If you're publishing a personal site, you can make your blog your home page. Just sign into the editing suite, go to the blog tool in the navigation settings, and click the link to designate the blog as the home page. The next visitor to the site will see the blog first.

This is especially useful if you want to point visitors to the most recently updated part of your site. There's no need to edit your regular content to post a casual or temporary notice. And regular updating of the home page is one of the main criteria used by search engines when they rate your site, and in many the rating governs your position in search results.
