Hacker News HD has been crashing for me for the past two months. The only way I can get it to work (for a day or so) is by uninstalling and reinstalling the app.
That is strange, Hacker News HD works fine for me and never crashed during my tests. I found Hacker News! (the app with the blue icon) to be very unstable.
I presented my findings at the HN Cologne Meetup yesterday evening and one attendant had the same issues with Hacker News HD. I guess I have to revise my conclusions.
