@akkartik @bouncepaw history and editability I think, I never really thought about this until now I suppose.
I guess a text file could be a wiki, but if the suggestion is "Using Emacs/vim-style file system navigation is just moving the complexity of a wiki engine into an IDE", I'd feel a bit duped.
@neauoire @bouncepaw "search for word at cursor" is a pretty simple thing. I wouldn't call editors that provide it IDEs.
But yes, that's what I meant by "foundational" above. Wikis are so simple that every computer is a wiki engine.
Your point about version control is a good one. OP is outsourcing that to git. Which is reasonable, but I still consider version control quite complex. So I'm overstating how foundational wikis are..
