The Wikipedia article shows that a wiki that allows one to organize information similar to collaborative wikis except that a personal wiki is not collaborative.

I have been investigating the blogging, wiki, digital garden culture in the last few days to see what people who host their own websites do to organize their personal information.

I found some very good examples of digital gardens in this awesome Twitter thread - https://twitter.com/Mappletons/status/1250532315459194880

The first example in that Twitter thread is this wiki/garden - https://tomcritchlow.com/wiki/ - Garden, yes. But is this really a wiki? Can a simple tree of files be called a wiki?

I am trying to understand what is or isn't wiki. This might help me decide how I should name and organise my digital garden.
