Just when I'm sure I have nothing new to say, I see that other people are saying nothing new and getting talked about.
The particular insight that caught my attention came from a Lufthansa social media executive who declared that businesses should "Make your product your ads and your customers your ad agency."
Product has always been the first P of marketing and always will be and word of mouth is the best advertising money can't buy. But to talk about outsourcing your marketing is a dereliction of duty, even if you say it at a social media conference. Outsourcing marketing is what got us into a mess in the first place.
