Zynga feels like a firm without a purpose. The major difference between today’s Internet companies and ones that were founded during the dot-com bubble of the 1990s is that modern firms believe they’re changing the world. Though their claims may be dubious, Facebook and Twitter genuinely believe that they’re going to make a killing and they’re going to improve the lives of billions. By that standard Zynga is an unfortunate throwback to the best-forgotten bubble years. All the gaming company does is convince suckers to spend a lot of time and money tending virtual flowerbeds—and it didn’t even invent those virtual flowerbeds. If you’re looking for this generation’s Pets.com, Zynga is pretty much it.
