So you just found out that Google hasn't indexed your site, and you're upset. There, there.

Hey - why didn't you pick me up from the airport last Thursday? I know I didn't ask you to pick me up...but still! I was waiting & waiting!

Same concept. If you don't tell Google that your site exists then how the heck is it supposed to index you?

Simple solution...go tell them:

http://www.google.com/addurl.html

...then do some link exchanges for Pete's sake!
