It’s hard to remember a world without blogs. Originally a sort of on-line journal full of mundane personal updates, web logs have morphed into an extremely strong type of communication.

They were once shunned by the mainstream — now they’re the mainstream.

Whether it’s breaking technology news, an insider’s viewpoint, or irreverent humour you’re seeking, there are an infinite number of blogs on any subject whose authors will be happy to oblige.

It shouldn’t be any surprise that the technology world embraced the blogosphere far before every newspaper within the country started making their writers blog alongside their standard news stories. Consequently, there are blogs which are so great, so informative, so current — you’d be lost in your technology career without them. Here’s some we monitor daily. Add them to your bookmarks!

If you haven’t heard about “The Social Media Guide,” you simply could be living under an old Commodore 64.

If you’re looking for what’s next, look no further. Om Malik’s creation has grown into among the largest blogs worldwide, and it’s all due to focusing on what’s new. News and analysis on Web 2.0, technology and startups, social network, gaming — you name it, GigaOM has it covered. That’s what occurs when you’ve a team of 12 technology-obsessed writers (six of that have authored over 100 posts each).

In on-line terms, 10 years is a life time and 20 is an eternity. How long ZDNet has been in existence makes this go-to technology web site (previously “ZiffNet”) an anomaly among blogs. Founded in 1991, previously on CompuServe and Prodigy, ZDNet was purchased in 2000 by CNET (CBS Interactive), and reports on a wide range of technology news. While they focus heavily on the usual suspects (Apple, Microsoft, Google), ZDNet also features product reviews, software downloads and tons of news and analysis on technology businesses and issues.
