You know, I think you just answered a mystery for me, that is, why I fell so hard into fanfic back in 2007. I could read it “as I read as a child”, voracious and consumed by the story.
Most of what I read that isn’t fanfic is non-fiction. It takes a lot to push me towards a fiction story, these days. Non-fiction gives me those “long reads” of succumbing that fiction rarely does these days. I don’t know why I am willing to suspend disbelief for fanfiction but not as often for original fiction, but there it is.
