Justin Uberti reports from Google's Kirkland office that Google Maps will soon include a new feature:
click-to-call. If a business has a phone number, you'll be able to call it for free through Google. You just have to enter your phone number, Google calls the company and you'll get a phone call from that company (without giving your precious phone number to that company). The feature is already available in Windows Live Local.
Update:
the feature is live.
