I write as much as I can (blog posts, iTunes U courses, iBooks) in the Markdown language. I am writing all of these blog posts and pages in Markdown because it is a simple way to write for any output that needs formatted text that could lead to the web or print. I use Workflow to convert each one of this blog's posts to Rich Text so that I can then copy and paste the Rich Text files into iTunes U Course Manager and iBooks Author. The Workflow conversion of each post occurs right after I post them to my blog. The process takes less than 30 seconds and will save me hours of rewriting and/or re-formatting the text. I think this is the perfect example of how iOS automation simplifies working on iOS and can save us time.
