I think this comment by Brandon Burns made on Fred's blog puts things in their proper context. I feel like a point is still being missed: mobile is a channel, not a product strategy. Instagram worked mobile first because you use it to take pictures, which you do on your phone. You also use your phone to order a taxi, and to connect with friends when out — Uber and Foursquare. Google still has more activity on the desktop than mobile; why? Because people don't like executing intensive searches on a small screen. Viral content driven platforms do better on desktop; why? People look at and share content mostly while goofing off at work, on the computer on their desk. Your product defines how you execute it, not the channel. Chase user behavior, not press headlines that say "X sector is growing!" Think like an experience designer, not like a VC.
