Very intriguing articlein WSJ today "On the Web's Cutting Edge, Anonymity in Name Only". Ths article talks about the emerging area of predictive analytics and how easily it is becoming to aggregate public information about you and make it available to marketers.
It's a fine line between intrusive marketing and personalized online experiences. I'm especially intrigued to think about where predictive analytics will help marketers go in enabling marketing and brand-building on mobile devices. Lots of buzz these days about location based services, but the combination of context based information, location and predictive analytics is going to usher in an amazing new era in personalized information and experiences.
