Nonfiction, because they're still describing what we observe, even if what we observe is made up. For example, literary criticism is nonfiction, even though the subject itself is (usually) fiction.
@medigoth If you wanted to respond to that person you quoted specifically, you'd best just use the Reply feature, or mention them in your response. A Quote doesn't automatically inform the quoted person.
@medigoth Yeah, this is the normal reply where you start a conversation thread.
The @-thing is not quoting but a mention. Just so you know!
@trinsec, thanks for your patience. :) Does this reply look normal?
@medigoth Yup! As you can see, if you click on this post, you can see the posts before that were responded to. A proper conversation thread. :)
Welcome to the Fediverse!
@trinsec, thanks!
@medigoth You can still go and give Crazypedia's original post a proper reply if you want to interact with them. :)
@trinsec Okay, I went back and looked: I didn't realize the Reply feature quoted automatically. Still learning my way around.
