I keep thinking that the entire country of Japan inhabits a space-time distortion that puts it 5-10 years ahead of the rest of the planet. It’s a place where novels written on and for the mobile phone make it onto the bestseller lists. Here’s how one successful author of mobile phone fiction explains the popularity of the genre:
They [Japanese twentysomethings] don’t read works by professional writers because their sentences
are too difficult to understand, their expressions are intentionally
wordy, and the stories are not familiar to them.
I don’t see this taking off in the States, mostly because Americans aren’t accustomed to reading anything on their phones longer than “whr u at?”. Maybe the notion of a literary form specifically tailored to electronic devices is an intriguing one.

I don’t think I could stand deciphering “lol hai i got ur txt” for 200+ pages (?), but in a way I see this as a modern version of the epistolary novel.
