Writing good, original content is hard. Which is why I love these two example filled posts by Ann Smarty about reusing existing content in clever and creative ways.
The first article on repackaging content looks at ways that you can repackage your content into formats such as presentations, PDFs and cheat sheets.
The second article delves into how you can repackage your content into an image-based format, such as a comic, a flowchart, or a comparison chart.
Both are well worth a read if you are finding new content ideas hard to come by.
