“So what if, every time you made an explicit, exaggerated thumbs up gesture, your moment in time was bookmarked?
Say, at a restaurant. The people you were with, noted. The location, saved. What you ordered, recorded. Everything in context gets a +1.
You won't remember what you had for lunch or who you were with or where you were, but next time you're in the area and hungry, the system remembers and points it out.
Maybe it also puts ambient recommendations back out there. It posts a review to Yelp for you, notes what you ate and the cost. It tweets and updates your Facebook status with where you are and who you're with. It posts a photo to Flickr.
And that's all you have to do to save a moment in time for later. Is this useful Y/N?”
