A major feature is that fans receive casual daily messages and photos sent directly by the artist and can reply to those messages. In contrast to SNS, where interactions are mainly in open spaces, bubble allows for exchanges in personal, dedicated talk rooms. This makes it possible to experience a feeling akin to conversing while sharing the same time, making the artist feel closer. Many globally active artists are strengthening their bonds with fans by communicating in spaces exclusively for their own followers. ▽ Main Features - Real-time messaging with artists - Automatic message translation feature (supports 14 languages) - User nickname customization
