Enhanced distribution allows your blog’s public content to be included in the WordPress.com firehose.
The firehose is a stream of the public data (public posts, comments, etc.) that flow through WordPress.com (and Jetpack blogs that participate in Enhanced Distribution). The firehose is used by companies and people who are interested in public blog content. When these firehose users display content from your blog, they are required to link back to your blog.
