Why? Because now instead of just writing down a note I started thinking about what terms do I want to make links and maybe go through previous notes to do the same. Of course you don't have to do that but the whole promise of the system is that the more you connect the more value you get.
I've dealt with this problem a lot (for example it's the same with going through lot's of rss feeds to categorize articles for later reading) and it's always about book keeping taking more time than an actual action.
After that I started thinking what was the most important about note for me. Actually it wasn't connections it was about the sole fact of taking a note (it has a higher chance that I'll remember it) discovery and ability to take a not from any where. A laboratory journal of sorts.
In my particular case discovery is easily covered by git grep and since I use plain markdown files I can always edit it offline with vim or online via github/gitlab web ide. Since it's only one file I don't even need to think about file names. The structure of notes is pretty well defined so it shouldn't take too much to write a script that would generate a digest for some term.
