Zemanta is a technology used by bloggers that inserts automatic links, adds relevant photos, adds links to related articles, and automatically tags your posts. The technology is available either as a browser plugin or a server-side plugin that supports either WordPress, Movable Type, or Drupal. However, I recently learned that it’s available as a Windows Live Writer plugin, too!
After installation, the Zemanta plugin will appear in the right sidebar of WLW where you can see the content it is suggesting for your post. (You have to write at least 300 characters before it will provide any suggestions.) The plugin works on Live Writer versions 12-14. You can see what version you run by going to “About” from the “Help” menu in Live Writer.
To try the Zemanta plugin for yourself, you can download it from here.
