Feeding Drupal in Real-Time

This document discusses using the Feeds module in Drupal to import content into a site in real-time using PubSubHubbub. It explains that Feeds allows importing content from various sources into nodes, users, taxonomy, etc. but typically involves periodic cron jobs. PubSubHubbub allows setting up a publish/subscribe system so that when content is published by a source, like new check-ins on Gowalla, Drupal is notified immediately instead of waiting for a cron job. It demonstrates importing geotagged Flickr photos and seeing real-time Gowalla check-ins on a map as they are published.
