Anyone who has spent a moderate amount of time on the major social networking sites will be well aware of the vast amount of gurus and charlatans advertising themselves as social media experts. Their very actions and methodology belie them as frauds. So many exist that we are now inured to their solicitations and dismiss them as sad-case nuisances. The guys and gals who simply 'don’t get it'.
However, genuine social media experts do exist. Men and women who have put in the long hard hours at the computer, in the library, in the field doing research and can legitimately declare themselves competent to speak of what they know - but they are few and far between. If the academic world doesn't wake up, they are going to be even fewer and further between.
