Some organisations, fearful of untoward consequences such as reputational damage, ban social networking websites – Facebook and the like – from their premises. Others embrace them enthusiastically and try to persuade others to do likewise.

One such is IBM; not the IBM which cowed the computer industry back in the 1970s through a mixture of fear, uncertainty and doubt but a global IT services company with a manufacturing operation attached. It is, in fact, one model of a modern interconnected company.
