This is something I wanted to try for a while cause 9:16 is filming in portrait which for certain shots looks much better than landscape. However in filming its very different however cause of the iPad or tablets you could easily watch a movie sideways. But its kinda has it own charm plus having a digital magazine with few moving images this way is quite interesting. Also in portrait it also nice to show people in portrait cause landscape you only get to see so little or you have a full body shot but have allot of open space for the background. Too bad Youtube isn't really good in handling or showing 9:16 but luckly Vimeo does a good job with it.
