Is there anywhere online I can track Santa's progress as he delivers Christmas presents to all the good little boys and girls around the Earth? For that matter, his sleigh must be rockin' fast: has anyone ever calculated how fast it'd need to go for him to deliver presents to every child between sunset on the 24th and sunrise on the 25th of December?

Is Santa Claus real, or just something us grownups invented to keep kids guessing about the presents they receive on Christmas morning? It's a question that I wrote about on my blog a few years ago (see Is Santa Claus Real?) and since then have been delighted to receive literally hundreds of comments, almost all from children, talking about their own beliefs and their "proof" that Santa is or isn't real.

I thought that in the spirit of Christmas it would be fun to just share some of the more amusing and poignant comments that have been added over the years.
