Bluesky, the emerging social networking app, has surged into the top 5 on the U.S. App Store, gaining half a million users in just one day. This organic growth has been catalyzed by dissatisfaction among X users due to recent policy changes regarding blocking and data sharing. Bluesky is also experiencing significant international growth, ranking high in various countries, including Japan and Taiwan. Meanwhile, X's recent updates have resulted in a drop to No. 29 in the App Store. The changing landscape highlights the ongoing competition in social media.
