Show HN: Google+ for Google Apps / GMail (noosbox.com)

Interesting app, but comparing it to Google+ is a bit of a stretch.

Do you feel the 'group' method of sharing conversations (as presented in this app) is a better way of sharing information across a team than the Google Circles method? I would worry that in a workplace setting, people wouldn't be sufficiently motivated to set-up and use circles effectively.
