php Link Directory Mods has developed an rss feed mod that will greatly benefit your directory and the links that are submitted.
What this mod will do is add a section on your submit page for link submitters to optionally add an RSS feed from their blog or articles if they have one.
Then on the details page for the link there will not only be a link to the blog or articles page but also the latest feed from that page will be displayed on the details page giving each details page unique and freshly updated content. This feed is automaticlly updated everytime the blog is updated or new articles added.
Below is a sample of what a blog feed would look like.
