The new Blogger solution for auto summarised posts, also known as "Read More" or "Jump Break", is becoming increasingly popular in Blogger blogs, for several reasons. Auto Pagination resulted in display segmentation , caused by the perceived need to publish hundreds of posts on the main page. Desire to display a dynamic index of posts as the main page. Desire to simply make the main page and / or archive retrieval displays smaller. The "Jump Break" feature itself is reasonably easy to use , when you are using the New Post Editor, and with blogs that use a template released after Jump Break was released - apparently in September 2009. If your blog was created before then, you may need to add a critical bit of code to the post template .
