User blog comment:Foreva/HxH is rich and quite popular, why are there so few articles on Hunterpedia?/@comment-5261894-20111110150952

Because HxH is virtually unknown overseas. No one really read it or watched it because it was a dated series. Despite being so popular in Japan, it hasn't so much as made a dent in the US. All of the other series (sans Dragonball) are more recent and consistent works with fanbases that stay because a product is continually being made.
