Personally, I think the best one was the GymRats article, here's an excerpt:
"Like outdoor climbers, we gym rats have a highly developed culture, which exists in it's purest form in gym caves, where rat deities are born of overhangs and high v-grades. Cave rats have two defining characteristics: We are prone to worship fellow rats who send v-hard, and we never climb alone. We travel in packs, to ensure appropriate spots, to secure inter-group beta, and to maximize fun. The pack serves a fourth, all-important purpose - it wards off wandering beta-wolves."
This is critical stuff for any indoor climber.
