LinkedIn is the only site I use.
I would be very interested in the result of the poll though Jono
Is that possible?
LinkedIn is the only site I use for business.
I use Facebook privately and the others for business, although a lot of our clients do.
I use Facebook for personal, but recommend it for some clients. I also promote blogs for clients, but don't write my own. I use and promote Twitter and LinkedIn.
Whilst I use Facebook it isn't for business. All the others I use for business.
