How would you launch a Yelp-like site?
lallysingh: Yelp's got a lot of space for improvement, you can do well here.For example: the iPhone app doesn't let you write reviews.  The best time to write a review for a place is when you're there.  But Yelp wants me to go back home and log in through a desktop to do that.  EPIC FAIL.Do some use case & scenario analysis, and you should do well.  Consider plugging into different parts of peoples' lives.  E.g. Facebook and the iPhone.  A facebook app that browses reviews of people you know, and lets you invite people to a restaurant for dinner could do pretty well.
