Further refinement to Globe&Mail recipe

Thanks man, it's a great start! I tried to refine it somewhat further.
Key changes:
  • Removed more "value-add" content from the article (social and related links, etc.)
  • Fixed multi-page layout issues, should always full the full article now
  • Fixed sports and auto feed naming
  • Fixed commentary feed link
  • Added code to find and eliminate duplicating articles across multiple feeds (i.e., the same article showing up in Business and Investing)
  • Added Toronto section
  • Changed cover image

Outstanding issues:
  • Failing articles: ~5% of articles randomly end up being empty, any ideas on how to debug?
  • Articles with only media content, would be great to identify and eliminate

Thoughts? Comments?
