But my blog is 0.9, and the RSS library still can't read it. If I 
understand your message, the library shouldn't be doing validation, but 
it seems that it is. Am I calling it incorrectly?

   fail response.code unless response.code == "200"

   rss = RSS::Parser.new(response.body)

   result = rss.parse
   puts "Channel: " + result.channel.title
   result.items.each_with_index do |item, i|
     puts "#{i+1}. #{item.title}"
   end
