Here are some screen shots and some additional notes.
As you scroll, new pages are added automatically. A page break block is introduced between the page content to indicate that Auto Page is working and to provide options to pause auto paging and to restore the page.
When you 'pause', no additional pages are loaded until you click on 'continue'. You may wish to use the 'pause' if you want to see bottom of the original page which might keep scrolling out of view otherwise.
When you are reading blogs, the comments and the post comment form are collapsed so it's easier to read the main content. If you wish to read the comments, just move the mouse over to the 'Comments' bar and any comments to the blog post are automatically displayed. You may also click on the 'Comments' bar to always keep the comments visible. This feature has been implemented only for some of the popular blogs.
