Google+ gets more awesome each and every day. Jarkko O has updated us on a new feature to Google Hangouts Extras. From within any hangout you’ll be able to call anyone in the US and Canada for free. It uses your Google Voice number so you’ll have to have one of those setup. From there, it’s like the person is on Google+ with you even if they’re not. Pretty cool. Check it out at plus.google.com/hangouts/extras today.
