I was using Obsidian for some time back then. It was pretty useful to associate/graph information to each other, and convenient to write in Markdown format. The learning curve may be a bit steep for some users.

The problem was the capturing and organizing of information took a lot of effort especially when the information grew in time. If you can really make something that makes capturing and organizing information effortless then that would be awesome.
