Google has begun rolling out its "+1 button" for Australians. According to the Official Google Australia Blog, the +1 button will show for most users logged into their Google accounts by the end of the week.
The button, originally introduced for searches at Google.com in March, lets users of Google's search engine recommend particular sites by clicking +1 either on the site or in search results.
Google will list sites that people have voted for using the button in search results, tailoring the list shown to a user based on his or her contacts and people with similar interests.
The initiative met with a lukewarm response from social media experts when it was rolled out in the US "This isn't revolutionary. It's actually fairly evolutionary. It's a 'me-too' move, catching up with what Facebook has done," Altimeter Group analyst, Jeremiah Owyang, said at the time. "It's not a huge leap forward for where Google needs to be in the social space."
