Sounds like an interesting idea, but how do you create an anonymous space where the trolls can't fester and grow? I like that she's considering those people who build a social media following and then send their followers to mass attack or mass block people they disagree with, but the question remains, do people want to be anonymous?

Didn't Silicon Valley already try an anonymous social media/blogging platform for industry people to gripe about their lives without risking their careers?

Or the larger question, how much should a personal opinion be held against someone's career?
