Video-sharing app Viddy just had its Bieber moment. Justin Bieber has joined the service, tweeting his handle yesterday and encouraging fans to follow him on the service. And just to amp up the buzz, he then posted a video of himself in a topless photo-shoot. “Photoshoot was….well u will see. #viddy #abouttogoIN,” tweeted Bieber. He already has more than 20k followers on Viddy, with that first video getting 12k likes and nearly 3.5k comments. Previous social services to have high-profile Bieber moments include Twitter – which famously had an entire server devoted to Justin-related traffic – and Instagram.
