Adrian has a nice piece here on what they've learned at Zeus Jones in trying to make marketing a service
I particularly like this:
"the flip side of turning marketing into something that’s useful for
customers is to find a way to turn the things you’re already doing for
customers into marketing"
Mark, note and inwardly absorb, as my old Headmaster used to say.
BTW They've got lots of other great stuff at Zeus Jones. And they're great guys, too. Go make friends
