There's an interesting dichotomy which seems to be arising here. It's almost as if he's defining a folgezettel note in opposition to orphaned notes, most often seen in digital settings when importing lots of "stuff" but which Doto indicates can happen in analog systems as well.

Orphaned notes in an analog space, however are still linked by proximity even though they're not as densely linked (even from a mathematical topology perspective.)

Experimenting can be interesting. I've tried using spreadsheet software like Google Sheets or Excel which can be simple and useful methods that don't lose significant functionality. I did separate sheets for zettels, sources, and the index. Each zettel had it's own row with with a number, title, contents, and a link to a source as well as the index.

Google Docs might be reasonably doable, but the linking portion may be one of the more difficult affordances to accomplish easily or in a very user-centric fashion. It is doable though: https://support.google.com/docs/answer/45893?hl=en&co=GENIE.Platform%3DDesktop, and one might even mix Google Docs with Google Sheets? I could see Sheets being useful for creating an index and or sources while Docs could be used for individual notes as well. It's all about affordances and ease of use. Text is a major portion of having and maintaining a zettelkasten, so by this logic anything that will allow that could potentially be used as a zettelkasten. However, it helps to think about how one will use it in practice on a day-to-day basis. How hard will it be to create links? Search it? How hard will it be when you've got thousands of "slips"? How much time will these things take as it scales up in size?

A paper-based example: One of the reasons that many pen and paper users only write on one side of their index cards is that it saves the time of needing to take cards out and check if they do or don't have writing on the back or remembering where something is when it was written on the back of a card. It's a lot easier to tip through your collection if they're written only on the front. If you use an alternate application/software what will all these daily functions look like compounded over time? Does the software make things simpler and easier or will it make them be more difficult or take more time? And is that difficulty and time useful or not to your particular practice? Historian and author David McCullough prefers a manual typewriter over computers with keyboards specifically because it forces him to slow down and take his time. Another affordance to consider is how much or little work one may need to put into using it from a linking (or not) perspective. Using paper forces one to create a minimum of at least one link (made by the simple fact of filing it next to another) while other methods like Obsidian allow you to too easily take notes and place them into an infinitely growing pile of orphaned notes. Is it then more work to create discrete links later when you've lost the context and threads of potential arguments you might make? Will your specific method help you to regularly review through old notes? How hard will it be to mix things up for creativity's sake? How easy/difficult will it be to use your notes for writing/creating new material, if you intend to use it for that?

Think about how and why you'd want to use it and which affordances you really want/need. Then the only way to tell is to try it out for a bit and see how one likes/doesn't like a particular method and whether or not it helps to motivate you in your work. If you don't like the look of an application and it makes you not want to use it regularly, that obviously is a deal breaker. One might also think about how difficult/easy import/export might be if they intend to hop from one application to another. Finally, switching applications every few months can be self-defeating, so beware of this potential downfall as you make what will eventually need to be your ultimate choice. Beware of shiny object syndrome or software that ceases updating in just a few years without easy export.
