Many running Google+ Pages for their companies have likely been frustrated by the lack of interaction with some of their fans -- if visitors haven't already put the brand in a circle, they've been off-limits regardless of their interest. A quiet change may have just opened the floodgates. Pages can now share, comment on and +1 posts from those who weren't already followers. Google hasn't made the change official, but it is promising a feature that's ultimately complementary: Pages should get their own analytics for demographics and social activity in the "coming weeks," giving owners an idea as to who they're attracting. While we hope that the loosened restrictions don't lead to unwanted conversations in our feeds, they're undoubtedly valuable to companies that just want to share good news or offer a helping hand.
