As an aside, Lifehacker seems to be eating my back button on Chrome. Even selecting HN from the history would just keep reloading the page and wouldn't bring me back to where I wanted to go.
I wish more developers would stick to a pure web approach instead of going the app route. Quite often i find the lack of integration with the web of a native app to be a dealbreaker.
