Key points for the new Google + pages:
1) Google's +1 button will not automatically subscribe anyone to a brand page. Rather, Google is introducing a new button that brands or publishers can use to allow visitors to join a circle in one click.
2) Unlike Facebook, Google won't attempt to derive any direct ad revenue from Pages, though they will be tightly integrated into search, Google's ad products and analytics.
3) Pages will soon be location-aware, allowing local businesses to send offers and deals to mobile phones.
4) Google will allow Pages to have "Hangouts," basically one-to-many conversations in a defined group.
