the article you clicked on was most certainly not submitted by nodejitsu.
news.ycombinator has a long history of squashing articles and submitters that aren't funded by y-comb.
most of this is done through their "silent" banning and censoring mechanisms, that leave people not even realizing they have been silenced.
i hope you enjoy this article, and remember that HN is extremely biased and that you should keep your horizons broad."
While I would agree that HN is bias towards YC-funded projects I would not agree that it is biased against non-YC projects or news. In fact, the majority of the items on HN are non-YC. This also follows for submitters and commenters for the year or more I've been here.
On a different note. Hpricot is not representative of Ruby scraping anymore - nokogiri (http://nokogiri.org/) is where it's at. Which has a Hpricot translation layer if you need to change. Even when I decided to solidify on Python for everything else I will still go back to Ruby just for nokogiri when it comes to scraping.
