Hacker News is a fantastic site for tech/startup news, but the experience of browsing and participating on the iPad was simply frustrating. This app is not just an RSS reader for the site. It provides the top news list, and automatically loads both the article and discussion with one touch. It also supports upvoting and downvoting straight through the app navigation bar.
