With the number of blogs continuing to climb (Technorati currently reports 21.1 million blogs), more and more bloggers are wondering if there isn’t some way to make all that hard work pay. Once again, Darren Rouse of ProBlogger comes through, this time from his deathbed. In an post titled How Bloggers Make Money from Blogs, he details several varieties of advertising, sponsorship, affiliate programs, digital assets, blog network gigs, non-blog writing, donations, selling your blog, merchandising, and consulting. If the topic is of any interest, this is the best round-up I’ve seen. Even with a high fever, Mr. Rouse knows whereof he speaks, having reported a six figure income from blogging last year. Not all of us can aspire to the same rich trove, but it helps if you at least know where the potential lies.
