Facebook may indeed be the perfect channel for transmitting “word of mouth marketing”.

The only problem with word of mouth marketing from a marketers perspective is that you can’t legally buy it without disclosing you bought it and word of mouth as a rule can’t be replicated or scaled.

So while Facebook may be the perfect environment for the incubation and distribution of word of mouth, marketers who rely solely on Facebook users to create and distribute positive word of mouth in their behalf may find themselves without a marketing job.
