Where to submit your startup?

I have launched my first start up ever, Poucher (http://poucherapp.com) and I can say among all the things I have tried Hacker News, even though without a single comment, helped a lot with the traffic.

Here comes my question though and I'm sure many people like me tried to figure out the answer. Assuming that you've just launched your startup, weekend project or hobby how would you get it heard?

Which site would you submit your startup that takes less than 10 minutes. The reason why I am pointing out the 10 minutes is because most sites require 48 hours to review your project.
