Just had a look at my google webmaster account it says the last time google crawled my site Googlebot last successfully accessed your home page on Apr 28, 2008 Whats going on
I'd say the reason for this is because you have no backlinks, therefore google can't crawl your site. In order to be seen by google, your site must be on a site that is crawled by google. Altought you are visible on google, your site might be indexed very rare ... for more info I recommend you use the help section from google webmaster tools
