At the end of this month, we are putting on a Mobile First CrunchUp , which will focus on the increasingly popular strategy of creating a mobile product first, and a regular Web product second, if ever. Mobile is just a more interesting part of the Web right now for many reasons—iPhone/Android, tablets, location-aware apps, cell phone cameras, GPS. People are so interested in this topic that tickets sold out before I even announced any speakers. Well, if you bought a ticket, you won't be sorry because the speakers are awesome. Joe Hewitt, the former Facebook engineer who created its iPhone app—one of the most downloaded of all time—and then left Facebook to pursue a more native HTML5 approach to creating mobile apps, will talk about native versus mobile Web apps. Omar Hamoui, the founder of Admob, which he sold to Google for $750 million, is now doing Churn Labs, which churns our one mobile project after another. He was doing mobile first before it was cool. Instagram CEO Kevin Systrom built the most popular photo-sharing app with hardly a Web presence at all.
