"I couldn't believe some of the responses. There were tons of people saying that their iPhone apps were because they made it easier to find restaurants.. or that their B2B social media marketing startup was because it was improving productivity for marketers. I'm paraphrasing but that was the gist of many of the responses. Don't get me wrong, I have nothing but respect for people who have successful typical startups. But that said, I think people sometimes are extremely sheltered if they think that those sorts of problems are really impacting lives."
