Well Google Places that we used to know is no longer here. If you follow the search engine news, you probably already heard it. It is pretty big news. Now local business will need to set up a Google+ account to get there pages. Also Google is using Zagat (which they purchased a while back).
As I too am figuring out the changes, I have put together a list of articles that I have been reading on the subject and thought you might like as well.
