Richard Laermer has just published a book on trendspotting called "2011: Trendspotting for the Next Decade". It's about how you can learn to pick out useful signals from all the noise around you, and what to watch out for over the next few years. One particular reason for highlighting it is that it's free. Laermer believes the future is about information openness and has convinced McGraw Hill to publish it free online.

I'll be reading it over the next few days and will put up a review when I get a chance. In the meantime here's a video of Richard being interviewed by the guys at Mashable, discussing his ideas and future trends.
