A great new app for mobile social networking, LBS and recommendations in this post on Technology Review (MIT). I love Magitti even more than Whrrl as it is a more integrated and holistic way to give more relevant recommendations using social network analysis more elaborately.
Furthermore, the below quotes touch upon the importance of lifelogging using mobile phones as a way to authenticity, self awareness and filtering. In my view clearly the way forward, followed up by tight integration of key life goals and aspirations in the long run.
"The idea of community-generated reviews is, of course, not new. The
popular recommendation service Yelp, for example, is already integrated
into Google Maps. And the concept of locating friends using a mobile
phone has also been around for years; Loopt, a service that runs on
Sprint and Boost Mobile phones, is one of the most common examples.
Whrrl, which can also be downloaded onto BlackBerry Pearl, Curve, and
Nokia N95 smart phones, is commonly compared to both types of service.
But it differs from either in that it combines aspects of both. In
addition, Vengroff explains, Whrrl has collected details on
establishments in 17 cities, which allows the service to provide
fine-tuned local search, letting the user narrow down the hunt for,
say, a café to one that has outdoor seating and vegetarian options and
is recommended by at least one friend.
In the future, she suspects, location-based services will include more predictive features. For instance, instead of explicitly requiring you to write a review, the software might recognize how often you visit a restaurant and infer that it is a favorite. "Eventually, I think that a whole lot of exciting technology will emerge that figures out how to reduce the burden on the user," Choudhury says. "There will always be the case where user input will be important, but when we find the sweet spot, that's when I think it will take off."
