" summary

foursquare grows from a tiny team to ~32 people while turning checkins into actionable city data: badges and mayorships layer game mechanics onto real-world behavior and drive users to change habits (gym badges, pizza crawls, mayor discounts). a tips system crowdsources micro-recommendations about exact dishes or basement exhibits and a web button pushes itineraries into the phone. an open API spawns apps like WePlaces, a cab‑share matcher, Mob Zombies (100 local zombies), and Assisted Serendipity, proving the platform works.
