Like the volume feed described in Listing 1, this feed contains a set of elements, each representing a book in the user's library.

While every individual blog has its own RSS and Atom feed, the volume of posts and the number of blogs make it difficult to track what discussions are going on in the Intranet on a macro-scale.

First, these services can only process a limited number of feed items per day so the transformation may not work with high-volume feeds.
