Ars Technica
Who runs it: A cadre of tech writers and geeks, mostly from Silicon Valley. A journalistic and serious approach to current tech issues separates Ars from the more typical tech blog resources.
Why you need it: Knowing about the newest gadgets or rumored software updates is great, but if you’re looking for a more long-view approach to the world of technology, and how it affects your world, whether or not you count yourself a geek, Ars is it.

TechCrunch
Why you need it: Considered by the tech community at large to be the best place to stay in the loop on what’s new and soon to be, TechCrunch attracts nearly 2 million unique visitors every month. Their database of new media companies and entrepreneurs, including the newest of the brand new startups, is invaluable.

Hulu
Who runs it: Hulu is NBC Universal and News Corporation’s online video joint venture.
Why you need it: The fastest-growing video site on the Web focuses exclusively on professional content and does not take on YouTube directly as a viral video destination. It use may provide the model for how we all watch television in the next 10 years.

Scobleizer
Who runs it: Robert Scoble’s blog. Scoble is a former Microsft maven turned self-made monster of new media.
Why you need it: An early-adoption mentaliity has made Scoble a valuable resource, tutor and sounding board for the rest of us, as he covers gadgets and software most of us don’t have the time to try out ourselves, never mind learn about in the first place.

Engadget
Why you need it: Ah, gadget porn. If that’s your bag, this is your site. Leaked shots of unreleased consumer electronics — cameras, game consoles, phones — you name it, it’s all here.

Kotaku
Why you need it: There are countless video game sites out there. Some focus on previews, reviews, video, cheats, discussion. Kotaku is my favorite as it samples from all of the above with its straight-up blog roll architecture. Visiting the site daily ensures no gamer will miss out on the next great title, especially from lesser-promoted publishers.
