I'm a mobilebeat startup challenge finalist, and I have no idea what to expect

Around 3 months ago, I asked for a review of my application, BlogRadio. http://news.ycombinator.com/item?id=1200506 I got some good comments and good direction on how to further enhance the service. I have been quietly working on this for some months now, and now we have made it to the finals of Mobilebeat. http://venturebeat.com/2010/06/30/mobilebeat-2010-startup-competition/

This is by far the furthest I have ever gotten with any of my ideas or side projects. I am both excited and a bit nervous.

I plan to reach out to some of the other finalists and understand how they plan to approach it. I have not been very good about networking with other founders. I have been to a few meetups in San Diego, but it seems the 'scene' here is not as robust as Silicon Valley.

I'm looking for opinions on how you would approach this.
