User blog comment:Foreva/HxH is rich and quite popular, why are there so few articles on Hunterpedia?/@comment-3039150-20111130184645

Probably because the newer shonen manga characters (especially the villains) have this habit of explaining all their abilities (in full detail) to their opponents in the middle of battle, in hopes that they won't leave their enemy some clue on how to beat them, sometimes flashbacks about past lives occurs a lot too that would last 140 chapters.and don't forget the UMA mascots with strange creepy faces one for each main character =D

But Joking aside though I think the main reason is that the despite it's age, it really does not have that much chapters yet and it is still on-going. As it was already mentioned the Hiatus does not help either. There is just too many unknowns (so expanding an article may prove challenging in sometimes). Casual fans that have watched the anime series at it's peek of popularity may have forgot the juicy details for it and wikis are still not exactly that widely used back then. The Official data book was not made available for English readers either afaik The Manga is still going strong in Japan, there were many purchases on the latest tankoubon (volume) release, the art is also better in these versions than the one you see in scanlations, sometimes there are some extras on those too.and just DavisWTG said other wikis can have a tendency to scatter info around too much into multiple articles that could be rolled into a few ones.
