Google only shows links from pages with a
PR of 4 or better, but that does not mean you don't have the links, just that they are not reporting them.
Your site does not show many links when using the LinkPop tool, a total of 89 links webwide and only 5 in Google.
It would be a good thing to submit your site to as many directories as possible, and to engage in a link campaign to improve your links, which can be very helpful to your rankings if you use good anchor text in the links, and make sure you use the same URL for your address, (i.e. use the www. in front of the URL always) as some search engines will see them as different pages otherwise.
