I've been using Logseq for the last few months and it's wildly better for me than using things like Evernote for this. I used to be big on having a lot of structure in terms of notebooks and notes, a lot of which contained project journals of one sort or another. But the way Logseq makes journaling a primary interface makes things much easier. I tag some things I want to be able to find later, or link them to pages. But I have a lot fewer dedicated pages now, and have to worry a lot less about maintaining consistency in some sort of broad ontology.
I use paper. Sometimes I refer back to the last few pages but rarely go back further than that. 99% things... Seem like really good ideas but if they don't stick then they probably don't need a dedicated home. And if they do stick.. well, I'll have to flip a few pages and copy them into my personal wiki or something so they can have a longer life.
