I recently taught a workshop on crisis communication at a top business school. Afterward, a mid-career executive came up to me with a question. But it wasn’t about how to handle rogue employees, or industrial accidents, or philandering CEOs. Instead, it concerned a far more personal sense of crisis: her overwhelming fear of public criticism if she became active on social media. She was an accomplished professional; she’d run an environmental consultancy for the past six years. And she knew some kind of web presence was necessary for her credibility. “You have to have something up there for people to find you,” she said. “Having nothing would be bad.” But her web presence was spartan, a throwback to the “Web 1.0” days of static, brochure-like sites. Anything else, she feared, might risk opprobrium.
