What should I put in my navigation?

[narutodude000]

I want to make my website, http://linksku.com, like Digg.com (links to other websites and a community). However, it's more targeted at teens than Digg. So far I have
ENTERTAINMENT
HOBBIES
JOKES
LIFESTYLE
NEWS
SCIENCE
SPORTS
TECHNOLOGY
OTHERS
LINKS (for guests)

What should I remove/add?
