There are quite a few blogs that I read for news and information about subjects that interest me.
My favourite at the moment is Lifehacker, which mainly covers ideas for making you more efficient or effective. Some are tips for DIY or saving money but the majority revolve around technology, particularly how to get the most out of software. Another favourite is TUAW, The Unofficial Apple Weblog, which covers Apple news and reviews. For information focused on new hardware I read Engadget.
My interest in productivity, which is one of the reasons that I like Lifehacker, surfaces again in Zen Habits. This is a more esoteric site, sometimes verging towards hippyish, that nevertheless has some good articles on subjects like “How to manage your inbox”. I will post links to these when I find them.
