Yet, it feels like a personal wiki to me. :)

I think that a focus on low level tools (javascript), or on current and common implementations as the definition of wiki, is unnecessarily restrictive.

I was going to "count the ways" that Miki can be considered a personal wiki. It doesn't much matter. It works for me, and I hope maybe a few others.

Instead, I'll propose that Miki, and other tools like it, are in the realm of personal wiki, in a similar way that Unix is an IDE. https://sanctum.geek.nz/arabesque/series/unix-as-ide/
