Google Maps has a new feature to enhance local search offering; letting actual Google users leave reviews on business listings.

From the Google Lat/Long Blog: Google Maps has offered a collection of reviews assembled from some of the finest sources on the web for some time, but now we're augmenting those with reviews from an even better source: you -- and, we hope, millions of other opinionated Google users.

It's very simple to add reviews (you'll of course need a Google account to get started). Just search for your favorite places (restuarants, shops, grocery stores, your dentists, etc) by name or address and click on the "More Info" link if it's available. From there, click on "Write a Review" and start giving your two cents.

If you've got a local business with a Web presence, it would behoove you to solicit existing customers to leave a review on Google Maps as soon as possible.
