With so many self-professed social media “gurus” these days, it would serve us well to be able to distinguish the ones worth listening to from the ones that are bullshitters.
The brilliant Sam Ladner, PhD wrote in her 
blog:
The bottom line is this: social media bullshitters have no knowledge of social theory or methodology. Trust a person who provides no easy answer, who carefully selects their research method, and who understands complex concepts.
This is basically the same criteria for the evaluation of all “experts”. Beware of those with the easy answers…
