If you have the time to follow only a few technology blogs a day, these will generally give you the most bang for your click.
Slashdot: The granddaddy of the tech news blogs, and the virtual water cooler of the geek cognoscenti. To be "slashdotted"--that is, to be noticed by CmdrTaco, ScuttleMonkey, or one of the other regulars--is in some circles the Net equivalent of above-the-fold placement on the front page of the New York Times or the Wall Street Journal.
Engadget and Gizmodo: The Bobbsey Twins of the techie gadget universe. If there's a cool new phone, PDA, game console, DVR, or other device brewing, you'll hear about it first from these guys. We only wish we had their inside sources.
TechCrunch: Founder Michael Arrington worked as a lawyer to tech startups and has started a few Web entities of his own. Thanks to those contacts, he often has news of an interesting new Web service before the rest of the world does.
Ars Journals: The blog arm of the venerable geek site Ars Technica offers an intriguing mix of news, opinion, and hands-on trials.
ReadWriteWeb: This site may not have TechCrunch's buzz, but it's at least as good a source for news on the latest Web 2.0 developments.
Scobleizer: Robert Scoble was Microsoft's most prominent blogger, putting a chubby, friendly face on the software giant, until he left a year ago. He remains relentlessly upbeat and personal as he covers technology happenings.
