19 February Title 2nn 3. Techcrunch Techcrunch began in 2005 as a blog about dotcom start-ups in Silicon Valley, but has quickly become one of the most influential news websites across the entire technology industry. Founder Michael Arrington had lived through the internet goldrush as a lawyer and entrepreneur before deciding that writing about new companies was more of an opportunity than starting them himself. His site is now ranked the third-most popular blog in the world by search engine Technorati, spawning a mini-empire of websites and conferences as a result. Business Week named Arrington one of the 25 most influential people on the web, and Techcrunch has even scored interviews with Barack Obama and John McCain. With a horde of hungry geeks and big money investors online, Techcrunch is the largest of a wave of technology-focused blog publishers to tap into the market - GigaOm, PaidContent and Mashable among them - but often proves more contentious than its rivals, thanks to Arrington's aggressive relationships with traditional media and his conflicts of interest as an investor himself.
