Korean-Japanese Telecom Tycoon Masayoshi Son earned his place as the CEO of Japan’s largest mobile phone company and the second richest person in Japan through aggressive expansion of his interests.
That personality often comes through in his Twitter account too. Son recently had to defend himself via Twitter after a half-million-dollar donation to Hurricane Sandy relief irked some people.
That’s the great thing about Twitter, isn’t it? You can now directly give Forbes’ 53rd Most Powerful Person in the world a piece of your mind. But don’t expect him to take it lying down.
That’s what @kingfisher0423 learned when he tweeted to the Softbank CEO: “With the degree that your hairline has receded, you are bald.”
