Nice. Forum members think so too.
Not only that, but the Google Webmaster Central team has announced that Google is rolling out code search sitemaps - that is, you can "create Sitemaps that contain information about public source code you host and would like to include in Code Search."
And if your sitelinks aren't your first choice, you can provide feedback to Google on what you want changed.
It is only getting better from here. :)
