There is a fundamental difference between an organisation’s Public Relations and that organisation’s public website.
The first is designed to control the conversation. It looks to create a monologue and shut down any public discourse.
The other is about creating a dialogue, a relationship with the user.
Have a look at websites that are controlled by the PR department. Most Corporate sites fit into this category. They are filled with pdfs and press releases.
It feels like a public relations bookshelf, and what a lonely, cold place that is.
They do not try to control the voice, but to try and be part of the conversation.
