2bits released a new module today.
It is called clean feeds.
Currently Drupal's feeds contain all the markup, including the HTML tags for images, hyperlinks, ...etc. This can cause a site to lose clicks when users click on external URLs included in the feed.
Most sites do not include links in their feeds.
This module is designed to address this, and make sure that when users are interested, the site owner will not lose traffic.
Note: for Drupal 4.7, a patch to the node.module is required. Check the patches directory included with the clean feeds module for a patch as well as a pre-patched node.module.
Drupal 5.0 handles this properly, so there is no need for a patch, but the module is not ready for that version yet.
