I posted that question on Quora and got no answers, sorry to say. But in the meantime I was researching the answer in connection with the creation of an app based on GoFISHn.com, which is a user-generated content site about fishing I started two years ago.
We're calling the app, "The Best of GoFISHn 2011," and we're building it from the best of the more than 10,000 posts members made on the site. It's gorgeous and unlike anything that's ever been tried in the fishing media world. The app (think interactive magazine, or picture book) has about 50 sections, and they feature the images and video from some great fishing guide members of GoFISHn as well as sections we dreamed up based on compliations of great posts in areas like world records, celebrity, danger, disasters, invasives, and more. Below is a sample screen layout from an early prototype.
We've learned a lot in the past two months putting this together and working with Dmitry Paperny at Cohere Studio, so I wrote up my own answer to the question. It's not comprehensive, but it's a good starting point. I hope it saves some time and effort for folks on the same track.
I am beginning to understand how moblie,and tablets in particular, will change everything.
