Creating 'After the jump' summaries

I was looking for tutorials on how to put read more for some of the posts that might be too long. Then I found Expandable Post Summary for the New Blogger (formerly beta) from bloggertipsandtricks. First attempt with the html. Voila! But then, I just realized that I was abit "lagging" because blogger has improved alot and that we do not need to alter the html code but just use the feature 'jump break'. So, this post is an example. Both method  are working.
