We told you about Google's +1 recommendation button when it launched in the US back in April. Now Google's attempt at adding a social interface to search is officially hitting the google.com.au domain.
Google's local blog notes that the +1 option should start showing up for Australian users this week. As with most Google products, the rollout is gradual, so you might have to wait a few days (I can't see it yet myself).
The usefulness of +1 remains very much open to debate — it relies in part on data in your Google Profile, and for many of us, the last thing we want is to give Google more personal data than it already has. Keen on the idea? Think you'll give +1 the thumbs down? Tell us in the comments.
