These tools (this, foam, obsidian, remnote, supernote, etc.) seem interesting but I've been hesitant to try any. This HN comment[0] on a Foam post a few weeks ago resonated with me. I feel like my ideas and personal knowledge base in my mind is really dynamic and that the constant addition of information and rearranging or establishing of new relationships between entities will be too much effort.
I think, at least for my use, a more simply knowledge base (e.g. zotero, are.na, etc.) where I'm able to store, categorize, and search for things is the best option, and I'll leave the establishment of relationships to my mind.
