Social Networking

I recently got an invitation to register on the latest social network Google+. Don't expect a full appraisal of it, but from what I can gather it's much like Facebook except it enables you to group your contacts so you don't have to share everything with everyone.

I joined Facebook when my son was away at university as a way of keeping in touch on an informal basis. Since then it's enabled me to make contact with relatives all over the world - one or two cousins in different continents I'd never met. I've also connected with other writers, but as far as networking goes it hasn't been much use to me.

I think Twitter is better for networking because you can follow just about anyone so it's useful for knowing what people are doing and thinking.

Do you use them, and what do you think?
