I have a piece on WorldChanging today about using Drupal's Aggregator2 module as a news tracking tool. The piece was partly inspired by a recent inquiry about why to use Aggregator2 rather than Drupal's default:
Aggregator2 turns the Drupal platform into a powerful tool for news tracking and republishing by offering options for customizing news feeds, tagging news items, and moderating incoming news. That feature set makes Aggregator2 an exceptionally flexible choice for setting up a nonprofit news tracker that aggregates news from a wide range of blogs, news sites and search engines. Because Aggregator2 saves each individual item as an independent node (like a web page) in Drupal, you can edit or annotate news items after you bring them onto your site. Because Aggregator2 lets you assign different tags to different incoming feeds, you can set up different news pages for different topics, and direct news to show up on the appropriate pages. And Aggregator2 is also a terrific tool for integrating content from multiple related web sites or overlapping organizations.
