Google+ is available as part of Butler Google Apps.
Keep in mind that if you already have a Google+ profile under a personal Google account, your Butler Google+ profile will be IN ADDITION to your personal profile - meaning you will have two Google+ profiles.
The Google+ team is aware of this and is looking into ways to merge accounts when students graduate. Just be aware that the two accounts are separate.
Google+ is NOT another Facebook.
Facebook is a SOCIAL network, where you friend your family, friends, coworkers, and other people with whom you have (or had) a real-life connection. It's meant to keep up with your contacts, find out who's doing what, share funny pictures, etc. There is some actual content sharing like Google+, but it's pretty hit-and-miss.
Google+ is a CONTENT network, where you follow like-minded people (mostly strangers) who share your passion: landscape photography, quilting, model railroads, cross-stitch, teacher education, etc. It's meant to share information with other people who are interested in a particular subject, and share it ONLY with those people. There is some socializing like Facebook, but it's mostly within these areas of shared interest.
