If its so awesome why didn't you mention it? You have to promote it, and you don't always need money.

The eat your own dogfood axiom is a good method for starting out. Post about your app on places where it is relevant, how it has helped bring about alignment of the planets and increased your bowling scores, etc. If it is highly interactive and fun to use or watch it being used, make a youtube video on "Get Ninja (insert category of app) Skillz With Easy App X"

If it is crowd sourced thing maybe run a contest to gather content/interest, don't have to blow ten grand on it, only a few hundred and some well placed shout-outs about the contest.

I myself like to look at videos and screenshots of apps (ohhh... shiny stuff!) You have a site with screenshots??
