Scott Adams is a clever marketer when it comes to promoting himself and the Dilbert brand.
I noticed he had partnered with a company called SkyScrapes to sell Dilbert merchandise after he challenged his blog readers to take pictures under the product. He would select winners and post those pictures to his blog.
He also shamelessly promoted (the best kind of marketing!) his last book on his blog. The book happened to be a collection of his blog writings.
And, Mr. Adams is also on the forefront of Widget technology, as evidenced by his newly colorized Dilbert strips in a shiny new online-embeddable widget format (see below). What makes his marketing tolerable is that he is often willing to give away something of value (his comic strip or a free ebook such as "God's Debris") to popularize his brand and entice customers to buy something else (i.e. Dilbert branded merchandise or a book sequel such as "The Religion War").
Hats off to you, Mr. Adams for trying out interesting new ways of melding marketing with technology!
