Huge kudos to the entire team at foursquare on today’s release.  This is not just about the incredible amount of work that has gone into building the release (and for iOS and Android simultaneously to boot).  It is primarily about what I have called the “courage of big changes.”  This new foursquare release brings exactly the kind of big changes that take courage to make because inevitably there will be users who won’t like some or even all of them.  It would be so much easier to get trapped in incrementalism but that’s not what startups are about.  I am thrilled that foursquare is still behaving this way.  I also recommend reading Dennis’s wonderful post on his personal Tumblr.
