Seth Godin’s Knock Knock online marketing book now available

As promised when he released it, Seth Godin’s ebook KnockKnock is now available for free.

It’s a short take on how to use the new online marketing tools to make any website work more effectively.

I haven’t read it yet, but I’ve enjoyed Seth’s work in the past. All of his books have at least one powerful idea that makes the read worthwhile.
