I only recently started using Medium. I do like the audience aspect of it, but I also want my own personal website to mirror all of my content on Medium. As they don't have an API I'm actually working on something to periodically scrape my own Medium account and copy all the posts to my personal website so they can be seen at either place.

Although technically not that different from this project my objective would be not to switch over, but rather still use Medium's editor, but just have content mirrored.
