Google get's all social with Google +1

Google is now encouraging social interaction between Google profiles using it's new "Google +1" (similar to a Facebook Like).

According to Google:

The +1 button is shorthand for "this is pretty cool" or "you should check this out."

Click +1 to publicly give something your stamp of approval. Your +1's can help friends, contacts, and others on the web find the best stuff when they search.

Perhaps this is the first in many moves from Google onto Facebook's turf?
