There are two main problems with wikis : Maintaining and Finding.
I'll start with the second, because it is 2023, and wikis are finally embracing semantic search [0]. This will not only almost solve this problem, it will also alleviate the need for heavy handed content organization in general (categories..)
The first problem is best solved IMO with getting someone responsible for gardening it, as someone put it in this thread. There are products designed for smoothing the process [1], but a human gardener is still you best bet.
