That's an easy thing to say, but it's just not true. Seth hates promoting himself, it makes him uncomfortable, and he goes out of his way to avoid ever mentioning his own books or his startup on his blog. When he releases a new book he'll usually post a couple paragraphs from it on the blog, and that's about it. In the three years since Squidoo went into private beta he's promoted it maybe three or four times on his blog and probably mentioned it less than ten times total.
Alex3917 - I don't disagree. But, isn't Godin's approach still masterful self marketing? Being self-referential is tacky. So, justifiably, he avoids it.
My point: the fact that you know his style of promotion means he's self promoting. :)
Thanks for giving a more human side of the story. I think Godin is a very good self promoter, but I also think he's someone like Tom Peters: an out of the box marketer. He has different ideas, he can support them, but also he chooses a more shallow way of explaining them, probably to get them faster to the general public. I don't buy Kiyosaki for example, but Peters and Godin: they have interesting, original and honest ideas. I can't say if they are sooo great, but I think they might be useful sometimes.
Anyway, Godin's blog isn't very interesting, but the books are better, at least the ones I read.
