I have been in Seth Godin (marketing guru) mode for the past few months. I have been reading all of his books and am now addicted to his blog. I was pretty stoked to see that he has written a new ebook and is giving it away for free. There are three versions and one is focused specifically on Non-Profits! Go ahead, check it out, it don't cost nothin'... Seth's Blog: Flipping the Funnel--new ebook
By the way, I emailed Seth about a week ago in response to his post about marketing funnels. I sent him a copy of my article on the marketing funnel and look at this great reply I got:
"bingo. Thanks Michael"
Short and pithy, that's why he's the master I guess.
