An anonymous reader writes: The crush of news sites today is almost overwhelming. For true bits of news — bare facts and alerts that something has happened — it doesn't really matter which site you read it on. Some tiny, no-name website can tell me $company1 bought $company2 just as well as Reuters, CNN, or the NY Times. When it comes to opinion pieces and analysis, though, it's a different story. One of the generalist tech bloggers at the NY Times probably isn't going to have many worthwhile posts comparing database sorting algorithms or explaining the Cassini spacecraft's orbital path or providing soldering techniques for fixing a busted monitor. An example most of us are familiar with: Bruce Schneier generally provides good advice on security and encryption. So: what expert bloggers do you keep tabs on? I'm not looking for any particular posting frequency. This type of person I'm thinking of is probably not a journalist, and may not post very often at all — posting frequency matters far less than the signal-to-noise ratio. My goal is to build a big list of smart people who write interesting things — mainly for topics you'd expect to see on Slashdot, but I'm open to other subjects, as well.
