Publish creates an individual webpage on http://dayone.me for each entry you choose to publish. By default, you're the only one that will know the URL for each published entry. If you want to share entries with more people, you can post to social services like Facebook, Twitter, and Foursquare on a per-entry basis. Each entry retains social sharing stats and links, including views, likes, and shares. Learn more at: http://dayoneapp.com/publish.
