Local results, even when you're not logged in

Today Google announced on their blog that they are now serving up local results for terms that aren't necessarily "local" in nature. The new feature has been rolled out to all users world-wide. You don't even have to be logged in to a Google account to get local results now -- which some people might find disturbing.

Previously, if you wanted local results, you had to search for something like "pizza in seattle". Now, searching for something like "photographers" or "pizza" without any type of location modifier now shows you local results.

How does Google figure out where you are when you search for a term without a location? They look at your IP address and try to figure out your location from that. This isn't always the most accurate way to determine the location of a user, so they have plans to use a different method of triangulation with GPS or browsers plugins.

What do you think of the new feature?
