Back in 1988 ...
... I quit my 9-5 job as an IT boss, because marketing & management effectively stopped me from doing my job. After a year or so of looking for another 9-5, I realized I was making more money as a conslutant, bailing out companies whose management completely cocked up their internal IT infrastructure. In 1992, the company I quit paid me almost 30X what I would have made if they had just allowed me to do my job. I've been doing it ever since. It's quite lucrative. Try it, you might like it.
Marketing & management have no place making IT decisions, never have, never will.
Concur on "you need to have a social media presence" being pure marketing bullshit.
