What am I missing here?
But what you are missing is the cargo-cult of the youth which strife for a guide to imprison their thoughts. This method is really nothing new, not even innovativ. It originates from the same ideas which created the html and wikis later. But the last hype around hypertext was 20 years ago when wikis were new and hyped, and that didn't last long for technical reasons.
And now we have a new generation who rethinks the same methods again and create new software from them, which can finally fullfill the wishes which where 20 years not possible because of limitations in hard- and software. This is good in it's own, but the hype and ignorance is really funny in it's own. Especially if you are german and know the background better than those people who throw around words which they barly understand correctly, nor know it's history.
I don’t necessarily agree either that “more notes is better” as an absolute statement.
