How large can you go?
My current slipbox is about 8500 notes. Over the last several years, I've added between 1500-3000 notes per year.
Yes, some of these are redundant, unnecessary, or ill-formed. I've tightened and improved my focus for notes during this time. And as I find old notes that are unneeded, I archive them elsewhere. Sometimes I even devote time to going through and culling them. Since they are still findable via search, there's no reason to keep them in the main slipbox unless I intend to build on them and refine them. Still, my process of archiving unnecessary notes does not generally lead to any rapid decreases, while my process of note creation seems likely to stay at the same pace.
I have two concerns: a practical one, and a conceptual one.
Most significantly, will my tools be able to keep up? Even the Finder frequently lags and balks at large lists of files in a single directory. I haven't hit a wall yet with The Archive, but I do wonder if that and other tools will be able to keep up.
Less significantly for now, are there conceptual limits I should expect to hit? Have I perhaps hit some of these already? So far as I can tell, I've been able to deal with conceptual scaling by introducing appropriate systems and mechanisms, including things like structure notes and "tag maps".
