【明報專訊】EARLIER THIS MONTH Burson-Marsteller (B-M), a public relations (PR) firm well known in the world, emailed a blogger information on a social networking vehicle Google had developed in recent months. It asked him whether he would be interested to write articles criticising it and told him it could "help" him write articles and get them published in well-known newspapers and news websites. The blogger declined and made public the emails between them. A US newspaper has revealed B-M did so at Facebook's instigation.
