In mobile marketing era Many experts don't have technology, telecom, marketing background Do not know what they're talking about

As I saw with "social media" in 2010, many of the "experts" in today's mobile marketing field don't know what they're talking about.

Just got a "book" on it with many authors. Only about 20% knew what they were talking about, much like 2010 (and worse today) "social media experts."

Why does writing a book make you an expert and you can go to seminars and speak, disseminating wrong information?

Most of these mobile marketers don't have the background in telecom, wireless, and technology. Nor certification (I have an MBA plus CIW).

Working on a newspaper or television digital advertising staff for six months does not make you a mobile marketing expert.
