When I go to your site, there's a link to "visit my blog" and then it goes to a product page with no further links, just the address. It's kind of lame.. might want to just remove that and put a link directly to the blog. This might seem off topic, but I am just thinking of the fact that you are already promoting your site. Better to make sure there is nothing wrong with your site before you send a bunch of people there.
As for where to find young people - do you know any of these people? Or do you know someone who knows them? If so, why not make a survey and ask them to take it - find out what blogs they read, newspapers, magazines, etc. then focus your advertising on those areas.
