I spent some time today with the new android tablet beta app on a Samsung Galaxy Tab 8.4, which has a 16:9 aspect ratio. While browsing questions in landscape mode I noticed there was a lot of whitespace between the first and second questions on the same row. Example:

Seems like setting a "max width" for the first question would look better on wide screen devices, as you could see more of the second question.
Keep up the great work!
