I consider YabaIRyS more of an epithet than a nickname. I can't imagine anyone using it to replace her name like "I wonder what YabaIRyS (IRyS) is doing", only as a description replacing yabai like "Bruh, YabaIRyS (yabai)" in response to something she did/said.
Forgetting Faufau is pretty indefensible. It's been a long time, but that puts it in the same boat as Kronini and Sanana which I did remember.
I wasn't sure if Fuwa-chan and Moco-chan count as nicknames or if they're just how you say their names in Japanese. I guess dropping the last syllable is what makes it a nickname as opposed to just their real name + Japanese honorific?
The one case where I prefer video is when I know next to nothing about the topic and the other choice is mediocre to low-quality writing. Most people aren't great technical writers, and it's easy to skip over steps either because the writer assumes too much prior knowledge or simply because it takes effort to put that information in. On the other hand, videos are the opposite where it takes effort to cut stuff out, so you usually get all the steps which is what I need when I don't know anything.
If I have the option of a well-written, step-by-step tutorial though, or if I already know the topic and have a vague idea of what I'm looking for, then text is much better for being able to search/skim/go back and forth at my own pace.
