Google is Wierd

I was typing in random things in the google taskbar yesterday when I decided to type in names of my storybook characters. If you ever do that, it's REALLY odd. Websites in Greek and Arabic and Italian come up with your characters' names in them--names you thought you yourself invented. You begin to wonder if some person in a foreign country will sue you for using their name, if you publish your book/series and they read it. Yipes!
For those of you who have not checked out homestarrunner.com (should I put a "tm" or an "r" after that?), check it out. It's a hilarious site with random and funny cartoons. My dad's colleagues introduced it to me; it's god funny.
I have a question for all of you who write fan fiction: I just want to know why it's so fun! I've read some really good stuff on the internet lately (mostly Tamora Pierce fan fiction), but every time I try to write my own I feel like I'm just copying off the story's orginal author and choose instead to write my own stuff. I wish I could write ff and not feel wierd or guilty about it, because some of the best writing I've read is from fans of famous books.
TFATF,
