Google Plus Pages – How to Access Admin of a Google+ Page

After a few months of testing, Google+ pages are available. You can now create public pages for brands, products, local businesses and more by going to Create a Page.

Although it looks like regular user profiles, but there are differences:

• Pages can’t add people to circles until the page is added first or mentioned.

• Pages can be made for a variety of different entities whereas profiles can only be made for people.

• The default privacy setting for elements on your page profile is public.

• Pages have the +1 button.

• Pages can’t +1 other pages, nor can they +1 stuff on the Web.

• Pages don’t have the option to share to ‘Extended circles’.

• Pages don’t receive notifications via email, text, or in the Google bar.

• Pages can’t hangout on a mobile device.

• Local pages have special fields that help people find the business’ physical location. Learn more about local pages.

So finally, People can add pages to one of their circles, +1'd the page, and share it to their streams.

Example Page: Google+ Your Business.

I assume it is the same as a Person's page, you can follow 5000 entities. The equivalent in circles I am not sure, but as long as you put 5000 users within your circles, that is the limit. The number of users that can follow you seems close to unlimited though.
