In a way, I’m happy that Apple is acquiring Dark Sky, because it is a great weather service, and Apple probably wants to own its own weather information service at this point. It sucks that they will be closing their API to third party apps at the end of next year, though. Open, relatively inexpensive weather data APIs let a ton of interesting and beautiful mobile and web apps blossom over the past ten years or so, and that time is slowly coming to an end.
