I didn't even realize there was a contest until this morning, but I merged in qhoxie's pull request to news:yc (listed as "iPhone App" in the voting options) yesterday, and I have to say, it works quite well.

I'm in the process of submitting a build of news:yc with the search support to the App Store now, so look for it in a week or two. Thanks again qhoxie for the patch!
