Plans? I assumed lots of people were already working on this. There's already a lot of training data out there, and I suspect most users can be identified by use of a handful of uncommon trigrams and sentence stats. I know you can recognize things I've written at work because they have real em dashes—people rarely type with those.

You can pick me out because I use double hyphens -- the poor man's em dash.

Triple hyphens --- the LaTeX man's em-dash.

Earlier quoted context omitted.

Your example doesn't match the principles you highlighted. Obviate->remove is replacing a perfect-fit with a generic alternative. "Obviate" was neither a word salad nor complex, it was straight up (marginally) better. This was a tradeoff to appeal to people whose vocabulary is narrow, not improve comprehension.

Isn't that how communication works? Understanding your audience and "appealing" to them does improve comprehension for them.

Yeah, using words you're sure your audience knows just is communication, to me.

That said, there is of course a gray zone here.

I'm a big counter intelligence man, so I love deliberately inserting randomness into potential identification metrics. In the words of martha stewart, it's a good thing

You probably don't want to associate yourself with a convicted criminal as a deflection technique.

NSA already does this. "Stylometry" I believe is the term. Perhaps they used heuristics and algorithms so far? I would NLP was good enough for this years ago.

I taught this as a routine class project in 2018.

You can probably spot me at work because I use really simple words. I write obviate then I re-read and replace it with “removes the need to do $foo. Some writers at work forget that the goal of the written word is to communicate to the reader not impress them with word salad. I regard it the same as clever code (note: not the same as complex code) - written for the author not the reader.

"Don't use a five-dollar word when a fifty-cent word will do."

I would have sworn that was from Elements of Style but apparently it's a Mark Twain quote.
