Personal notes have value, but probably only to you, and there's no real need to implement a super-specialized subset when many wikis, brainstorming/mindmap, and note-taking apps already exist with many of the same features.

That's the main risk of being an entrepreneur because most ideas tend to be fatally-flawed somehow for the current market.
