The Porous Membrane
As a visual learner, the term ‘The Porous Membrane’ has made quite an impression. In reference to Social Media, it encapsulates the idea that conversations exist within an organisation and within that organisation’s market, and that these conversations are separated by a ‘membrane’.
The more porous your membrane, the easier it is for the internal conversation to inform and align with the external conversation, and vice versa.(http://www.gapingvoid.com)
