Blogo has a really easy way to send your content from WordPress/Blogger to your Medium blog, it's called a Mirror.
It gives you the ability to replicate any content you write on your blog to Medium in just one click.
It's simple to set up:
1. Access the Preferences window by clicking on Blogo in the Menu Bar and selecting Preferences.
2. Select the Medium blog.
3. To the right of the Blog list, click on "Configure Mirrors".
4. Choose the Blog you wish to Mirror to your Medium Blog.
5. Press Done, and you're done!
So from now on everything you post to these blogs, will automatically be published on your Medium account. But you can always turn it off by toggling the button in Preferences.
