WordPress.com has announced a new integration with Zemanta.
Zemanta is a revolutionary new platform for accelerating on-line content production for any web user. Any user-created text (a blog post, article or web page) is directly “read” by Zemanta, which recognizes all contextual content. Zemanta then combs the web for the most relevant images, smart links, keywords and text, instantly serving these results to the user to enrich and inform their content. What’s more, Zemanta can be deployed on all major content publishing platforms and web browsers through a simple plug-in.
To add Zemanta, go to Users > Personal Settings in your Dashboard. You’ll see a new option near the end of the page that lets you add Zemanta to your posts. Click “Help me find related content (images, links, related articles, and tags) to use in my posts.” Hit “Save Changes” at the bottom of the page.
