I've been doing some experimentation with integrating RSS feeds from my accounts at Twitter and Delicious. Drupal has a whole range of options for importing content or aggregating content from RSS. You can see the results of my most resent experiments on social media aggregation. Delicious.com can be very picky about what sites it lets pull in its RSS feeds. Sites hosted at Bluehost for instance, seem to be banned. How did I get around this?
