90% of HN-ers are wrong. Bloomberg was all about using computer technology to efficiently deliver business information to finance people. If it's not a tech company just because the target audience is finance people, then Facebook, Instagram, etc, are not tech companies but rather entertainment companies focused on teens and 20-somethings.
This is as good an illustration as any of how myopic HN is. Bloomberg isn't just a tech company; they're more technical than most (word chosen carefully!) of the companies YC funds.
