What is data science?

Although submitted later, for this submission:

http://news.ycombinator.com/item?id=1398402

the person submitting it has taken the time to trim the URL of all the crap that this one has:

  utm_source=feedburner &
  utm_medium=feed &
  utm_campaign=
    Feed%3A +
    oreilly%2Fradar%2Fatom +
    %28O%27Reilly +
    Radar%29
    &
  utm_content=Google+Reader

Please, people, trim the URLs and give the duplication detection mechanism a chance. It would make HN a marginally better place.

Alternatively, please, PG, implement the mechanism I suggested ages ago:

It's not perfect, but it would help keep discussions in one place instead of getting spread over multiple submissions.
