Why Voice + Obsidian = The Ultimate Second Brain

Traditional note-taking fails because it creates friction between your thoughts and your system. When you have to stop, open an app, and type out your idea, you lose momentum and often the idea itself. Voice capture eliminates this friction while Obsidian's networked thought approach creates connections between ideas that typing alone can't achieve.
