"It's because check-ins don't work. After the novelty wears off, nobody wants to check in. Nobody. Like those stupid plastic awareness bracelets, check-ins were a fad that flared briefly and is now completely, 100% over." Let's look at the upside of all of this though. And this is an important lesson which shows in part why it's not good to be to smart and know to much. Someone who knew better would know not to even try doing a foursquare type app. To much friction, little reward (long term) and "check-ins don't work". Someone who doesn't goes ahead and gives it a try, builds a company, and now pivots to something else which may very well work. Which kind of dovetails with the VC model. Don't try to hard to think what will work just make a bunch of bets on a team and keep your fingers crossed that something good will happen along the way to failure.
