1. Quora built the community which can answer a wide breadth of general questions
2. Integrating Quora with search will put information production on steroids(Right now..The connection of asking the question to a community in the context of the topic you are searching in google is not there..Integration will enable just that..)
This is exactly the problem with passbook.
User has to learn a new 'hack' to make his passbook useful..
Why does the user have to click 'Add to passbook' button from his email when Apple can scrape our email and surface the information directly?
can't we do this without facial recognition?
how about the application passively check-in the user(using gps) based on amount of time he has spent at a particular location(like > 10 mins?)
