Local Goes Live By Aaron Swartz

Google Local integrates yellow pages-style information right into your search. Search for pizza 54217 (Luxemburg, WI - Where I live) or plumbers Luxemburg, WI and up will pop a little compass with a couple results. Click the compass, and you'll get a full listing of nearby results, with distance, maps, directions, related web pages, phone numbers, and more. You can narrow it down by category and distance, and look at a map of all the results.

Google's really done a nice job of combining various sources of information for this service.
