RWW has a review of Glow: Location-Based “Feelings” for iPhone. Essentially you can enter your feelings on your iPhone, and Glow will somehow aggregate them with the feelings of others and put them on a map. It’s an interesting idea, and like Twitter or other augmented reality software, this one could end up taking off. If….and here’s the thing…it could take off if you could get more from it then you put in. One of the things I thing any such app should do is provide I high benefit/cost ratio. Users should think: wow, I want to use this, and even take the time to submit my status, because it provides me with alot of value. For example, with Glow, if enough people go to a place and report positive feelings, others might want to go and check it out. (Likewise with negative feelings).
I also think that iPhones and other devices should be able to gather some of this information automatically. Either through better sensors or through even faster inputs (e.g. if I had a bluetooth device I could quickly tap to send a signal).
Regardless of where this technology goes, I expect to see alot more of it in the future.
