I'm a huge fan of 2 community news sites - Reddit and the more technical/nerdy Hacker News by YCombinator. The former has a few tablet apps but Android users haven't had as much luck with Hacker News apps for tablets. The website, while fast and looking just fine in the browser, is far from optimal for those using a touch interface with its tiny links to discussions and buttons.
Enter the new HackNewsBot app by Jason Ostrander, designed specifically for Honeycomb tablets.
We have the independently scrolling list of stories on the left which can be toggled on and off to make room for the browser on the right.
