I have to agree with Author that fanservice is a term whose definition brooks no hijacking. The examples he gives of others abusing the term might better be phrased as “brainservice” and “engineerservice”, respectively. Pedantically, it’s [thing whose base needs is being serviced]-service. This is why I invented geekservice as a term; I think the song “it’s good to be a geek” is disturbingly accurate in it’s exploration of the primal forces that truly motivate our kind:
Belonging to multiple categories myself (geek, fan, intellectual, etc) I may be catered by various types of -services in different contexts. For the most part I tend to refrain from fanservice, though with my Ranma viewing entering season 5, I’ve pretty much caught up on my quota.
