#Web Content Scrapers:

##Recommendation:
- open-uri - http://ruby-doc.org/stdlib-2.1.0/libdoc/open-uri/rdoc/OpenURI.html
to be used along with:
- Nokogiri - http://nokogiri.org/ to parse through the HTML

##Notes:
- In the Ruby Toolbox, the top 2 are Anemone and Pismo, but they are intended for getting metadata from web sites, not necessarily the html content.
