It appears that Google is readying their new social network, Google+, for business enterprise users. Currently Google+ is not available for Apps users.
In the Web 2.0 Summit this week in San Francisco, a Google spokesperson acknowledged that their business, cloud suite would soon have Google+ as an option. Also, the company accidentally leaked the most recent design of Gmail, which will be a central part of the Google+ experience.
Enterprise customers may be a sweet spot for Google with their new social network, as Facebook seems to lack a certain acumen for business customers and the work lives of people--perhaps Google can find a work / life balance that is neither Facebook nor LinkedIn.
