Comment on: Show HN: I built a tool that watches webpages and exposes changes as RSS

This is directly useful for financial data monitoring. I've been thinking about watching specific elements on energy report pages (EIA weekly inventory releases, OPEC statements) rather than scraping the full page. The element picker + RSS output is exactly the right interface for that — pipe the change event straight into an NLP pipeline without the noise of a full page diff.The RSS question: yes, RSS is useful precisely because it's composable. It works with anything. Direct alerts are convenient but RSS is infrastructure.
