Right, agree with <10 sec rule. But, again, the main promise of second brain tools is to keep your "second memory" layer organized. Apple Notes are good enough for copypasting links and excerpts you want to make searchable later, right? So I assumed that Obsidian's markdown/hyperlink system should bring some benefits into organization.
For me, the value is somewhere in between. Priority number one is getting the data into the second brain. Afterwards try to do a little organizing but don't fuss around too much with it because I can always make improvements later (especially if/when I access it for a second time). That's kind of how the real brain works.
Sometimes you don't even need to take notes. Just the act of pasting in a link or a snippet from an article you read is enough to reference it in the future.
If you insist on making things clean, then you can use some sort of version control and review all the notes that you've taken once a week and organize them better. The most important thing is to take the note.
