Ruby Readability
Command line:
(sudo) gem install ruby-readability
Bundler:
gem "ruby-readability", :require => 'readability'
Example:
require 'rubygems'
require 'readability'
require 'open-uri'
source = open('http://lab.arc90.com/experiments/readability/').read
puts Readability::Document.new(source).content
Options:
You may provide additions options to Readability::Document.new, including:
:tags - the base whitelist of tags to sanitize, defaults to %w[div p]
:remove_empty_nodes - remove <p> tags that have no text content; also removes p tags that contain only images
:attributes - whitelist of allowed attributes
:debug - provide debugging output, defaults false
:encoding - if this page is of a known encoding, you can specify it; if left
unspecified, the encoding will be guessed (only in Ruby 1.9.x)
:html_headers - in Ruby 1.9.x these will be passed to the guess_html_encoding gem
to aid with guessing the HTML encoding
Readability comes with a command-line tool for experimentation in bin/readability.

Potential issues:
* If you're on a Mac and are getting segmentation faults, see this discussion https://github.com/tenderlove/nokogiri/issues/404 and consider updating your version of libxml2.
Version 2.7.8 of libxml2 with the following worked for me:
gem install nokogiri -- --with-xml2-include=/usr/local/Cellar/libxml2/2.7.8/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.7.8/lib --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.26
