I’m not convinced about the usefulness of this format, but I’ll reserve judgement for now. However, one thing I’m almost certain is that categorization and navigation by topic is a must-have; serendipity just doesn’t cut it (unless you have made some truly groundbreaking advancements in search). Btw, I searched quite a few keywords in algebraic geometry and found nothing; maybe you could look into converting the Stacks project (they even have an API[1]) into your format and contemplate usefulness in the process.

Another meta suggestion: IMO knowing who you are is usually pretty important for establishing trust in academic circles. Maybe link to your personal homepage on the about page? Right now all we get is a project-specific email so you’re basically anonymous.
