I have been using [Foam](
https://foambubble.github.io/) along with [GitJournal](
https://gitjournal.io/) for all my note taking. I believe this is the ideal setup for all my writing needs as
1. this offers support for Zettelkasten-like tags(although GitJournal needs Graph view implemented)
2. No vendor lock-in
3. Completely open-source
What is your current note taking setup? What are your thoughts on this particular setup?
