This week, we bring you the first in an ongoing series of interviews with platform builders. We're calling this series 'Innovation Engines,' and we kick it off with Jeff Lawson, the founder and CEO of Twilio, a company that's building a platform to connect apps with telephone capabilities. If you've ever used an app that connected you with a customer service rep via a phone call, it was probably using Twilio under the hood.
Plus, we tell you what to think about personalization technologies (and why marketers find it so difficult), the $25 billion mobile advertising gap, and Apple's strangely persistent support for the iPod Touch.
