So you can show others how you would have written it.
An online software/website where you give simple editing tools and a popular original article to anyone who would like to show their version of it – a version that can come to an entirely different conclusion, use a different train of thought, etc. The author of the new version can use any or all text from the original article, rearrange it, do whatever you like to it.
When you write your post you try to make it the best you can. The best headline, best content structure, best images and videos, etc. But you don’t know if it’s the best you can do.
Create multiple versions of your blog post, test them all, publish the best, and sell the rest to other blogs. It’s more work but you will get the best performing post and get paid for doing all the extra work.
