Reading Web Feeds (RSS, Atom) in Ruby - Pros and Cons of Web Feed Libraries

Hello,

I’ve published a mini tutorial on how to read web feeds (RSS, Atom)
using the standard Ruby library.

Full article @
http://rubybook.wordpress.com/2008/07/15/read-web-feeds-rss-atom

I’ve also included a list of alternative libraries to read web feeds
in Ruby. The lists includes:

o Simple RSS
o FeedTools
o rFeedParser
o Feed Normalizer

Any libraries missing? Comments for a follow-up article on the pros
and cons of the different web feed libraries or anything else welcome.

Cheers.
