Congratulations to Rafat Ali of paidContent, what an amazing story. His daily blog focusing on content has been acquired for $30 million by Guardian News & Media. The site was founded in 2002 and has become a  pioneer in the online news space, doing high-quality reporting about online media and digital efforts by big media companies. ContentNext has offices in Santa Monica, Calif., and Manhattan and operates several other sites, and also runs several conferences. This sale comes after the mid-May sale of Ars Technica, a much larger tech-focused site, to Condé Nast for a reported $25 million.
