I have been writing content for one of my websites called Website Homework for a while now.

Any thoughts would be appreciated.

As I keep improving it, some of the other people's "fresh-eye" opinions will be considered as important

There is no doctype which throws browsers into quirks mode:

Good catch, thanks
