It is also still a few months out, and things could change. But here’s how it will work.

On Twitter’s mobile app, there will be a new button in the center of the home row. Press it and you’ll be taken to a screen that will show various events taking place that people are tweeting about. These could be based on prescheduled events like Coachella, the Grammys, or the NBA Finals. But they might also focus on breaking news and ongoing events, like the Nepalese earthquake or Ferguson, Missouri. Essentially, if it’s an event that a lot of people are tweeting about, Twitter could create an experience around it.

“It’s around anything that’s interesting,” Weil explains. “It could be current events. It could be breaking news. It could be awards shows or sports. But also cultural events and moments — things around your location and where you are. There’s amazing content, for example, posted to Throwback Thursday every single Thursday. But it’s hard to discover it; you have to work as a user to go and find the best stuff, but [we] can do it easily and can package it richly.” Twitter Project Lightening - Event-Based Curated Content [buzzfeed.com]
