This is exactly me with Evernote, and my same thoughts reading this.

I wish Evernote had some sort of stats on notes: I'm sure I would find that 90% of my notes have never been opened. Some of them (e.g. warranty numbers, etc) are there just in case they're needed, but the majority will never be opened. I probably use the same 2% of my notes (< 30 notes) 90% of the time. (Lots of invented stats here, yes.)

The article describes an incredibly easy content-creation system, but one where you can easy create much more content than is useful. (It reminds me of the ease of taking hundreds of photos a day with smart phones, particularly if you're a new parent.)

Even when you want to find the information, I think this lack of structure makes it hard to do so. For example, the author has a note that looks like this:

    * Had a really good [[Super Tuscan]] [[Red Wine]]  
      * [[Dogajolo Tuscano]] from [[Tuscany]]

My understanding (from looking at the other examples) is that if he went to the [[Red Wine]] page (presumably to look up a nice wine to buy), he'd see

    December 3rd, 2019
      * Had a really good [[Super Tuscan]] [[Red Wine]]
    Some other date
      * Bought a [[Red Wine]] for [[so-and-so]]:
    Yet another random note about other stuff:
      * Buy some [[Red Wine]] for [[whats-his-name]]

Even the links that point to useful information don't have the information right there -- you have to click through for each link. And some of the references may not have anything to do with a good wine recommendation at all. So you have to edit the [[Red Wine]] page to make it a useful list, but that's what we do with Evernote already, and the linking part wasn't that useful.
