I don’t really know yet. I keep a Zettelkasten but it requires too much maintenance compared to what I’m using from it for writing and such.

I’m actually tinkering with an idea called Incubator using the Everlog app. The idea is that I write down ideas, then I add follow-up thoughts as a comment in the same thread. At the end I should end up with something that is useful and maybe Zettelkasten-worthy.
