Today, Twitter’s live-streaming app, Periscope, is getting an update. Still locked into iOS, the update is pushing some fine-tuning forward. When you head into Periscope, the streams from folks you follow will now be pushed to the top of the heap, making them easier to see in the sea of streaming. Periscope has also made some tweaks to notifications, turning off follower notifications by default. One potential flaw in Periscope, the ability to zoom in on your location, has been mitigated by the option to tag your location.
