Social media has been around long enough that if you have a business then you already have a Twitter or Facebook account, or at least you should. If not you need to get on board. Better late than never, I say. So if you are an absolute beginner, then I highly suggest Google+.
Google+ first started as an invite only network. This was a way for Google keep a handle on server traffic and work out bugs. Slowly people started gaining access through invitations from someone already on the network and small windows of open access. The last I checked you can now access by going to the sign up page at https://plus.google.com/ and use your Google account.
G+ has the best of both Facebook and Twitter worlds. You can follow people like Twitter or friend someone like Facebook. They introduce the “circles” concept, as in your circle of friends, which is very cool. Now you can have a circle of co-workers, family, friends, business associates, etc. When you broadcast a status you can select which circles to post to. Again, a nice feature if you want to announce a pool party to friend and family, but not business contacts.
