If you explain what holes you are filling which Reddit doesnt maybe we could answer. In the 10 seconds I spent on the site, I couldn't figure out what it is. Sorry it looked to me like a digg clone.

A couple of questions:

1) Links are categorised, but there seems to be no way to dive or browse the different categories?

2) What is the significance of the shink at the top?

3) How do I submit a link?

4) How do I mod links up or down?

Currently, far from being a reddit killer I think :/

The service is much like TinyURL in that we shrink URLS. We then measure the click through rate on the new short URL and rank the link appropriately.

We might expand to more categories in the future.

What, no unicode?

your about us section links to your personal blog. What is the site about, how does it work?
