You guys are funny! It just a fun way to refer to the number of posts you have. You get further on the sock as you post. Obviously mine says moderator or mod squad so you'll have to look at what some other people have. You'll have to post more to move up the sock. Or I guess down since this is a top down sock.
Knitting socks is cool. I thought, if I can knit a sock, I can knit anything. Not necessarily so, but I can knit a sock. I can even knit two at a time, toe up or top down. Now I need to get to that yarn that's waiting. I started with worsted weight yarn and made in-home socks to keep my feet warm. My GS decided he needed thick, short top socks for slippers and he got them. If the toe or heel intimidates you you can try stirrup socks. http://www.lionbrand.com/patterns/80004AD.html
