Your blog’s main page usually shows the entire content of each post. If your posts are usually more than 2 paragraphs, then your visitor will find it difficult to quickly find the topic of interest to him because he needs to scroll down a lot.
From this you will display only part of the post and if user wants to read full post , he clicks on the Read more! link and he will be redirected to full text of that post.This is useful when your articles are long.
Note : You should enable Post pages in Settings–>Archiving in order to make this feature work.

if(len>0)
postbody = postbody.substring(0, len);
