This hasn't been a great year for social media. Internet addiction has been a hot topic, as have privacy issues, and there has even been a movement to #DeleteFacebook.
Last month, Satoshi Miyagi, artistic director of the Shizuoka Performing Arts Center, which runs World Theatre Festival Shizuoka, joined that chorus of critics.
"Since SNS (social networking services) are often just used as a one-way monologue, I worry that our world needs to pay more attention to listening to other people's voices," he said at a press conference to announce the lineup of his annual festival.
