These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Deader Than Disco: Originally, they are a popular mangaka well known for their iconicshojoseries as well as their massive crossover series. However, over time their popularity begins to decrease starting with the poor ending of XX Xholic and Tsubasa and snowballs to the point that the mangaka's popularity are now just a shell of their former self completely eclipsed by the ShonenJumpdemographics.
As an example, Yűko (of xxxHolic) simply cannot keep her hands off her female clients or her assistant's female friends. She's partial to tilting their faces up while she leans down, making for an 'almost-kissing' pose at least once with each woman Yűko sympathizes with.
Moe: Many of their female (and sometimes male) characters are just too cute for words. There's even a convincing argument to be made for the idea that Sakura Kinomoto is directly responsible for kicking off the modern moe "phenomenon".
