This is something very important: Don’t focus on aplications (FOSS or not) but on open data formats and proper import/export mechanisms so you can switch applications easily.

That’s why I use Obsidian! It’s not open source, but all my notes are just… pre-emptively saved as markdown files on disk. If they fuck me over I can just leave and open it in literally any markdown editor 😭

If they used a proprietary format, I probably just wouldn’t have used them in the first place and would have had to use a shittier alternative.

I love obsidian, I wanted to send a donation, but they only sell merch with expensive shipping :<
