Announced on the Google AdWords Blog, which is a sign of things to come, Google is promoting six companies that are now offering tools for businesses to manage their Google + pages.
Google said, "Google+ is enabling six companies to test Google+ functionality in their management tools -- Buddy Media, Context Optional, Hearsay Social, HootSuite, Involver, and Vitrue." Google added, "These companies will offer a subset of their clients the ability to manage circles, publish to Google+, and monitor usage."
Google set up a devoted page at google.com/+/business/3rdpartytools.html for these companies and also said you want to add your tool, how to get in touch.
Anyway, I can go off on this a bit but I'll let you take the hints I dropped here and do that in the comments.
