I think that the next search engine built should focus on mood.
It would ostensibly already know where you were, since everything else already knows where we are. All you would have to do is now how you feel have some idea of that nature of the activity you’d like to participate in. Or maybe not even know the nature of the activity!
You’d open up your browser and head to this fabulous mood-based search engine. There is a prompt saying “I’m feeling…” and you would enter your mood.
Homesick
Adventuresome
Party Animal
Relaxed
It would be ultimate use of social media in its entirety – blogs, forums, twitter, facebook – you could use language indicators to decide the moods of people when they head to a place. By gathering mood data from tweets and reviews, you would surely be able to get a rough idea of how people feel about a place.
Let make it happen!
