No of course, that's what they do - but that doesn't mean it's easy. I was merely commenting (and not on your specific application, which seemed fine to me) on the general task of reading about ideas from a vast array of industries & niches. You have to do this context switch constantly and in a short amount of time make a yay or nay decision. It's tough. And again, it's not exactly reading for pleasure, like a novel. It's reading dense copy from developers. It's tough.
