I've used GQ for 18 months and, overall it does most of what you would expect in 2013. Beautiful content, acceptable navigation, and some nice feature that aren't available in magazine.
Of course, sometimes small changes or glitches can make you pull your hair out. For me, the most recent is the "my book" icon that pops up on the top right corner every time you land on an advertisement. I get what this app is trying to do, but from an UI perspective it's distractive and with no way to turn it off, it's unacceptable. It muddles the simplistic (and enjoyable) page by page browsing a user would expect. Imagine, while reading your favorite novel, every time you flipped a page, you saw a blinking light. At first, you would just ignore, then you would start anticipating it, then you would do anything to get rid of it (while mumbling about the downfall of society and yelling at the neighborhood kids to get off the lawn.) I digress.
Yes, this app I get it. You are doing everything possible to make me spend a few extra dollars on one of your advertisers products. And in some brainstorming meeting some Sr Mgr said " we need to make it easier or more convenient or increase rev" while really saying "I have no good ideas but I need to be heard"...
Bottom line, allow me to get rid of the "my book" icon, and I'll stay a customer.
