Hey HN, I've been using RefZoom and contributing to it for over a year now. Personally, I've used it to validate and organize health information regarding supplements, weightlifting, and overall wellbeing by categorizing white papers into hierarchical notes connecting directly to the source.<p>Others have used it for organizing their thoughts for their PhD dissertation, and others use it as ways of proposing new treatments by validating their claims through published research.<p>Thought I'd give it a share here!
