Like others I analyzed the language of the Satoshi posts and quickly noticed word collisions with posts of another contributor, Robert A. Hettinga. For example,
.......Right, exactly.
.......synchronisation (spelled with an 's')
.......etched
.......shenanigans
That is interesting, but..
1. none of those are super rare.
2. I (and others I'm sure) eventually start mimicking after talking to or reading from someone for a while.
3. If I were hiding I would make sure to remove my own previously shown idiosyncrasies, but not think of ones I'd picked up from others considering them standard.
