Looking for a good example of a 'River of News' implementation done in Ruby. Rails, merb, sinatra or any other web framework would work. I have a couple ideas about how to implement it, but would love to see how people would do it.
The implementation should load more items into the same page as soon the user reach the bottom of the document.
For more information about the 'River of News' format, please check this video about humanized reader at vimeo.
