There's more, but you can read it in the Discord thread. In summary: **we have more than 100 customers. How does that work?**

I never pretend that Johnny.Decimal is perfect, and one of the ways that the standard implementation 'fails' is when you have more than _n_ number of something. More than 10 _categories of thing,_ for example.

Or more than 100 of pretty much anything. One of my design principles is that you _don't_ have more than 100 of anything.

So, we need to adapt. What I'll do eventually is document these patterns formally, so I can give them names and refer to them.

I've done that for the first pattern I talk about: [multiple systems [13.01]](/documentation/system-expansion-introduction).

Until then, here's me thinking out loud. I'd like to do more of these: maybe one a week? [Send me](/21.01/) your questions.
