It depends. Using all caps sparingly for emphasis or in certain special cases might be okay, but using them frequently can be seen as shouting and might come across as unprofessional.
Well, 'caps psychology fanfic' could be about exploring the psychological aspects of characters in a story where 'caps' might refer to some sort of characters with capes perhaps, like superheroes. It could delve into their motives, fears, and how their minds work in different situations.
I don't know for sure as there's not enough information given. But if it's related to superheroes (assuming 'caps' refers to caped heroes), it could be characters like Superman or Batman. They are well - known for having complex psyches that could be explored in a fanfic.
Yes, I can. For example, 'ONCE UPON A TIME, THERE WAS A BRAVE KNIGHT. HE LIVED IN A BIG CASTLE. HE WENT ON MANY ADVENTURES.' This gives a sense of emphasis and can be used to create a bold and dramatic effect in the story.
One reason might be that all caps make the words easier to read quickly. Another could be that it helps create a consistent and bold visual style throughout the comic.
