Update: Hacker has an updated script. His message: "Although the previous version worked for me, I decided to rewrite the script, here: Blogger posts in chronological order, 2011 version. Please use this revised script, it is better :)
Blog posts are by default arranged in reversed chronological order in the home page, that is, the newest (latest or most recent) post right at the top and followed by older post. A very common request from bloggers is to have the posts arranged in chronological order instead, that is, the oldest post at the top to be followed by earlier posts.
Up till now, the best solution we had been able to offer is to ask the blogger to play with dates and time or alternatively, edit the template to add extra "add a gadget" and then make a "sticky" post.
Now apparently the David Merriman had come up with a Blogger Hacking: Chronological Order where apparently all you need to do is to copy some script and paste it into your blog template just before the </body> tag and it will make posts in the home page display in chronological order instead of the usual default reversed chronological order of blogs.
This Hack: Chronological order have long been awaited and while I tested it with a test blog and found it not to work for that particular blog, because this hack has been requested by so many bloggers, I am writing about it here in the hope that you will test it and proved me wrong. Do leave your comment about your experience with this hack
