Have you ever used Twitter? I receive Breaking news, sports, weather, school closings, traffic ...etc. tweets all in one location. I don't tweet but getting all of that information as soon as it happens can't be beat.
I follow MacRumors, ZDNet and other tech sites and get the latest info without having to go to the website. They always provide links that take you right to the article.
I agree with you on Ping. It needs to be accesible through third-party apps and a browser.
