Entrepreneurship expert Evan Carmichael says the combination of marketing and blogging is taking the internet by storm. He just released his Top 50 Marketing Blogs to Watch in 2008  on his website. "These guys aren't just the occasional bloggers," he said. "These guys live and breathe their blogs. If they're not already the best at what they do, it won't be long." His list is divided into 10 categories from building a brand to utilizing technology in marketing. The list includes John Jantsch, whose Duct Tape Marketing Blog has become one of the hottest destinations for small-biz marketing tips.
