That was a very interesting read DK, and pretty fab for being first-year and all. I didn't really notice many typographical errors, but then my grammar/punctuation is far from accurate, even now. Well done pally.
Were you amazed when reflecting upon what you wrote, your thoughts then, and how very little has changed? That's how I felt when I read mine again!
I almost don't want to post it; it's pretty amateurish in comparison, really. I'll wait, since I would like to read further comments on what you wrote.
You paper has me reflecting upon how far mankind has come over thousands of years. From star gazing as a means of finding direction, to TerraServer USA.
I liked your closing sentence, also. It was a nice finishing touch.
