Many note-taking systems encourage us to save conclusions: summaries, quotes, links, tasks, tags. These are useful, of course, but the things that keep me thinking are often not finished answers. They are unfinished questions.
A good thinking tool should let questions stay alive for a while. It should not rush everything into a folder, and it should not treat uncertainty as mess. It should record why something caught my attention, where I became doubtful, and which assumption failed during an experiment.
This is one reason I still like local Markdown and versioned content. They are not glamorous, but they are honest. You can see how an idea changed, how a judgment became more careful, and how a project moved from a sketch to something that runs.
If Lucen Blog eventually becomes a richer knowledge system, I hope it preserves not only answers, but the way questions grow.
