Having EVERYTHING in one big text file would scare me a bit. I've been using the open source app Joplin which lets you take notes in Markdown and am leaning toward one folder per month and taking individual plain text notes there.

The metadata is in a database but the notes themselves are all plain markdown. If something bad ever happens to Joplin, I can just dump the .md files to a folder and move to something else.
