Bridgy

Bridgy periodically checks social networks for responses to your posts and links to your web site and sends them back to your site as webmentions. Bridgy also translates the responses to microformats so that your web site can fetch and parse them.

Bridgy can also publish posts, comments, likes, and RSVPs from your web site to social networks. When you ask Bridgy to publish a post, it analyzes its microformats data and publishes it using the social network APIs.
