If you've been reading this blog for a while, you should already know who Mark Rippetoe is.
Zach Evan-Esch did a phone interview with him, and posted it on his blog right here.
After you've listened to that, take a look at the improved Starting Strength website. The articles are uniformly interesting, and they're a good resource for trainees and for coaches alike. The article on gear (PDF) is a good, thought-provoking example - even the barbell is technically gear, so where do you draw the line? I recommend bookmarking that site and reading if often.
