Buzz Marketing with Blogs has a great interview with Darren Rowse, a blogger and all round good bloke making big bucks through a series of blogs (17 to be precise: crikey! Its hard enough to maintain 1!).
Lots of good tidbits and advice for those seeking to make money from blogs. Notably it never mentions that he is an Australian blogger, although he does personally mention once that one of his blogs is about life in Australia: further evidence that geography is irrelevant in terms of success in the Blogosphere.
