It also leads to inventing terms like "content marketing", "inbound marketing", "growth hacking". Oh, the irony with the last one. A marketing term, to trick people who hate marketing, to do marketing...
I'm sure it pans out great for people like Rand Fishkin, Dharmesh Shah and Sean Ellis. The problem is, the people who fall for these neologisms get disconnected from the much, much larger marketing community. They get inside of an echo chamber. Instead of reading thorough articles, by authors which credentials are checked, claims are investigated and arguments - reviewed by peers, they get moz.com and quicksprout and kissmetrics, unbounce and optimizely. Well, I guess people get what they ask for - something easy, which does its "magic".
My last line in the previous post was a cheap shot and uncalled for. I'm sorry about that.
