That's the million dollar question: * An app that makes you see and use new tools and frameworks that appear on HN (preferably in contained VMs) A pdf reader that let's you search quotes on reddit to see what comments are about that quote. Binge-reading and listening eBook reader: challenge is not to break the chain between listening (preferably TTS) and reading.
