Agree with the gist of 1. & 2. but was hoping for a more analytic-scientific approach to measuring the impact of the HN Front Page. That is probably impossible though. If you invent github/sliced bread then hitting the front page might be the best thing to happen to your idea. If your profitable business of scamming grannies gets the same exposure it will probably be removed from the iOS/Android App Stores within minutes. Launching Dropbox here is likely somewhere in the middle.
