I like the idea of something like Notion but I have no idea how I would preserve my data or ever migrate it. I imagine you have to have some pretty complex stuff going on to have rich text, images, databases, macros and whatever else all in a file or notebook. Getting it out in some sort of format may not be too hard, but how would you ever migrate that to new software?
Am I over thinking this?
I know Obsidian stores everything in plaintext, but how would something like Notion or Affine (a self-hosted one) compare.


I try to go for simple data Formats, not least, because I can later reuse these second brains from my locally hosted ai much easier.
Also because I do not want my second brain to be on the clutches of any cloud company.
That’s kind of what I’m figuring out. I don’t want to put hundreds of hours into documenting and organizing my life so I can switch platforms and put in another hundred hours of migration effort. I’d rather use open formats from the start. That rules out some complexity, but I at least retain most of my freedom.
I really like markdown with possibly frontmatter for this reason.
