Recommended Book: The Magic Loop by Bev Galeskas
This amazing book is what started it all for me. In it, Beverly Galeskas clearly explains how to use Sarah Hauschka's ingenious technique of knitting in the round on one long circular needle.
"Socks and more" is right! Anything you can knit in the round, you can knit on Magic Loop, with no laddering, quickly, easily, and without using DPNs. Hooray! Thanks, Bev and Sarah!
