I'm curious about the evidence of demand for this. I'm used to seeing individuals saying "I work for X, opinions are my own" and of course anonymous "official" business accounts. Where are the people claiming to be posting on behalf of a business, that would be better served by officially linking them to it? Even linkedin, which is a social network for sharing your work life, dosen't have a "verified" membership feature afaik. Is there an angle I'm not seeing?
