Ask HN: Do you have a personal wiki?
I can not assign folders to notes. Many times a note belongs to multiple folders. Wikis are not hierarchical and make more sense for notes but they are complex. They don't store data in plain text (or Markdown).
Obsidian is adding features that most editors don't support which is kind of a vendor lock in. Typora is a great Markdown editor but that's all it is good for. Logseq is weird and doesn't work properly for writing plain text.
Do you put your notes, thoughts, code snippets in folders or use a wiki based solution? If so does it support Markdown (emphasis on Markdown because it works great with code) and store data in plain text files?
