I'm linked up to some great newsfeeds related to music production and sound engineering.  They are RSS feeds, so you can subscribe to them yourself if you have an RSS newsreader or start page that lets you subscribe to them.

Sound Recording contains the latest white papers posted at ITPapers.com.  Some very valuable information and concepts in there... and a lot of stuff I don't understand.

Record Producer has fresh content daily and proclaims that it has "All you need to know about Sound Engineering and Music Recording"... though, that's doubtful; they're still pretty cool.

And, you can't go wrong with Slashdot.  As they say, "News for Nerds, Stuff that Matters."  Great geek site.

Those are the best ones, I think... but, I'm always looking for more.
