Seth Godin is a remarkably savvy guy. In one short post, he has managed to build an unbelievable case for blogging as a launch pad for publishing a non-fiction book.
He also hints at a disturbingly simple strategy to get your ideas out and still make money.
Seth is living proof that there is no shortage of valuable ideas. He delivers more value in a single post than you may find in entire books. He is a master at promoting himself and his ideas far and wide and often.
I have had great results following his advice. I should probably read more of it. :)
