People often post something on their web site, then post a copy elsewhere so that other people will see it. The IndieWeb community calls this POSSE.

Bridgy Publish adds a hidden link to your post, and sends a webmention to Bridgy, which will create a post on the appropriate site. It also stores the link for display by Syndication Links.

The plugin requires the webmention plugin and will not work without it.
