Some myths just never die. Your earlier article prompted me to re-enter this debate as well. That "howstuffworks" article reminds me of an identical "debate" to debunk these myths that the late Bill Travis and I conducted in Components in Electronics, and that was way back in 1991!
I have written several blog posts on the subject. You can find the most recent artcile, which contains several related links, at http://the-world-is-analog.blogspot.com/2009/02/laser-turntables-for-your-vinyl-lps.html
