I stopped using reddit when they put a "USE OUR MOBILE APP OR DIE" message that cannot be closed conveniently on their mobile page. There is no possible advantage that can accrue to me by giving them app-level access to my device rather than running in my browser, which I trust far more than I trust them. They are literally a dynamic, partitioned page-ranking system, why in the heck would I ever let that escape the browser's sandbox?
I'm (obviously) not the target market, but I absolutely detest disingenuous behaviour like this.
