You've spent a great deal of time crafting and publishing the perfect blog post, are you getting all you can out of that content? Repurposing your content allows you to get more mileage out of the content you've created. It's not that there's extra work to be done, it's that you're able to get a lot more out of one valuable piece of content than having to continuously create new pieces of content all the time.
Content repurposing is an essential part of content marketing, not just on your website, but it allows you to branch out and find your audience on all the platforms and in all the places that they're hanging out, while at the same time saving your time.
