Speaking of successes and failures, I dislike it when it feels like I care more about an app or service than the developer or platform owner. It sets off huge warning bells and sends me looking for alternatives. Apple is starting to give me that feeling with Game Center. Since Letterpress launched, a game that depends entirely on Apple's Game Center application programming interfaces (APIs) for everything from matchmaking to gameplay, Game Center reliability has taken a nose dive. For several hours this weekend, I once again had more Game Center errors than successful turns.
