Itâ€™s a simple idea: look at the latest news, pick stories you want to follow, and get a notification when something new happens on that story.
The key difference is that updates are not delivered as traditional articles, but as bitesize updates. In other words, as a liveblog would.
You can read a complete story, but then you can ask to get notifications for new chunks of information – liveblog-wise – rather than getting newly drafted stories which irritatingly repeat what you know already. Liveblogging often starts from a mobile device, in this case the stories are also published in a mobile-native way – going full circle, but also allowing for sharing the story either completely or just a particular ‘point’. The whole news-reading experience on this app just seems fluid. It also reminds me of the ‘living stories‘ idea introduced by Google (complete coverage of an on-going story being gathered together on one URL).
The post on Online Journalism gives some other examples of innovative liveblogging. The author, Paul Bradshaw, also analyzes this trend in his book Model for the 21st Century Newsroom Redux.
