First, a pointer: This diary of a recording engineer has some interesting insights into the music industry. Some of it, you've probably heard before. Other details, you probably haven't. Interesting reading.
I'd also like to call your attention to this post from Howard Tayler, author of Schlock Mercenary. Here, he's taking on the NCAA decision to require the complete removal of Native American imagery from NCAA teams, completely regardless of objections from Native American tribes who'd like the teams that adopted their imagery and names to keep on using them, thank you very much. "How much momentum does this stupid PC pendulum have left in it, anyway?" Howard asks. Unfortunately, a fair bit yet, I suspect ... there are clear limits to wisdom, but sadly, none whatsoever to arrant stupidity.
( Never mind that bollocks, where's the introspection? )
