Why is notion the tool all the cool kids seems to like for this stuff? (Serious question)
I have heard of some people who have moved bag and baggage to Notion to even replace the likes of Dropbox and Google Drive. I'd be extra careful of being so tied to something you can't switch easily or walk out to another platform/tool.
Please do keep in mind how Evernote went from a plan of a 100-year note-taking to "what went wrong with that company".
