I am an avid sock knitter and decided early on that I wanted to try out as many different methods as I could find to determine which was my ideal. It turns out that what I learned from each style has proven to be invaluable in my overall bag of knitting tricks!
But I did find that doing two socks at a time on one long circular, per Melissa Morgan-Oakes' book, is actually my favorite. And I use the method whenever I'm doing two pieces that are the same, such as gloves, mittens, leg warmers, sweater sleeves, etc. It's wonderful not to have to count rows to make sure both items are the same length! It seemed that no matter what I did or how carefully I counted I always had one sock shorter than the other!!! But not with this method.
For fun, there is also a great method of knitting two at a time, either on circs or dpns, but working one INSIDE the other. Here's a link to the article from Knitty, and there are some video demonstrations on you tube if you get caught up. It's totally wild!!!
Whichever method you choose, have fun and enjoy. Socks, to me, are one of those wonderful pieces of civilization that really bring us comfort!
